• [Utilizing administrative data to enhance the Health Management Support Program for public assistance recipients aged <40 years: Lessons from Toyonaka City].

  Shoko Takemoto, Daisuke Nishioka

  Objective The Health Management Support Program for public assistance recipients is now mandatory at welfare offices nationwide and primarily targets recipients aged ≥40 years. However, limited access to data from other health and welfare programs that take priority over public assistance creates structural barriers to evidence-based health support. During development of its 2016 policy to optimize medical assistance, Toyonaka City identified fragmented data and unmet needs among younger recipients. Therefore, health data from other municipal departments were linked to visualize the health status of public assistance recipients. This report describes the data linkage process and summarizes findings on children and young recipients aged <40 years, thereby presenting program outcomes.Methods Data were obtained and linked to welfare-ledger records: (1) routine vaccination histories from the Immunization Division; (2) municipal health-check and cancer-screening records from the Adult Health Division; (3) infant health-check results from the Maternal and Child Health Division; and (4) school health-check results from the Board of Education. Descriptive analyses were conducted using the integrated dataset.Results Among 27 children who remained in public-assistance households throughout fiscal 2024, only 18 (66.7%) received the second dose of the measles-rubella vaccine; coverage remained approximately 60% during 2021-2023. Recipients in their 30s showed higher smoking prevalence, greater obesity, and higher blood pressure, lipid, and glucose levels than non-recipients. The 2023 cervical cancer screening rate was 4.7% (48/1,028 eligible female recipients aged 20-69 years). Infant and school health-check data also indicated persistently high rates of obesity and dental caries among children in public-assistance households.Conclusion Administrative data linkage across departments, supported by provisions of the Public Assistance Act, identified health disadvantages beginning in childhood and continuing into young adulthood. These findings highlight the need for life stage-specific health promotion for children and younger recipients. Toyonaka City is currently planning targeted interventions based on these results.

• Combining thiopurine with partial enteral nutrition promotes complete mucosal healing in pediatric Crohn's disease

  Emiri Kaji, Atsushi Yoden, Takahiro Namba, Satomi Nishimoto, Masano Otani, Takeru Okuhira, Keisuke Inoue, Tomoki Aomatsu, Daisuke Nishioka, Akira Ashida

  Abstract Background The combination of thiopurines and partial enteral nutrition (TP/PEN) is a common maintenance therapy for mild‐to‐moderate Crohn's disease (CD) in pediatric patients. However, no studies have investigated the efficacy of TP/PEN. This study aimed to evaluate the non‐relapse and complete mucosal healing rates in pediatric CD patients following treatment with or without TP, in addition to PEN. Methods This retrospective observational study included 39 pediatric patients diagnosed with mild‐to‐moderate CD. Based on the proposed treatment, the patients were divided into the TP/PEN and PEN‐only groups. The primary outcome was the relapse‐free rate between the two groups. Relapse was defined as a pediatric Crohn's disease activity index (PCDAI) >12.5, Simple Endoscopic Score‐CD (SES‐CD) score >7, Lewis score > 135, and/or abnormal C‐reactive protein levels (CRP > 0.15 mg/dL). The secondary outcome was complete mucosal healing (SES‐CD score 0) at 12–24 months. Results Although the difference in non‐relapse rate between the two groups was not statistically significant, complete mucosal healing rates were significantly higher in the TP/PEN group than in the PEN‐only group. Complete mucosal healing at 12–24 months was achieved in 7/21 (33.3%) and 1/18 (5.5%) patients in the TP/PEN and PEN‐only groups, respectively ( p  < 0.05). Conclusion Nowadays, more treatment options are available, and TP/PEN remains a viable option for the treatment of mild‐to‐moderate CD in pediatric patients.

• A Review of Japan' s Medical Care Reimbursement Programs in Primary Care from the Perspective of Social Determinants of Health

  Hiroko Sakurai, Kemmyo Sugiyama, Kakeru Iwase, Yoshie Yuuki, Mizuki Oonaka, Motoya Maeda, Alata A. Suzuki, Katsunori Kondo, Ai Noguchi, Daisuke Nishiok, Naoki Kondo

  There is increasing awareness of the need to incorporate social determinants of health (SDH) into medical practice. However, the extent to which the reimbursement system addresses SDH remains unclear. This narrative policy review aimed to evaluate the Japanese medical reimbursement system to determine whether and to what degree it incorporates assessments and actions related to SDH, with a special focus on primary care settings. We also explored the potential impacts and challenges of these programs in addressing patients' SDH issues. A team consisting of physicians experienced in clinics, hospitals, home care, social epidemiological research, and a community care nurse reviewed the current reimbursement system. They identified eight medical reimbursement programs for evaluation. Two programs directly included SDH elements ("Hospitalization and Discharge Support Fee" and "Guidance in Cooperation with Mental Health Care Fee"). The two programs were introduced in 2022. It was found that SDH assessments are often optional and need more clarity in their items; few programs offer SDH assessments in outpatient and home care settings, and there is no mandate for collaboration with community supporters. We found the Japanese reimbursement system has provisions for some programs involving SDH. However, significant challenges remain that require revision. This study offers insights and recommendations for addressing health disparities related to SDH in the future.

• Long-term effects of mHealth consultation services on postpartum depressive symptoms and the mediating role of loneliness: A follow-up study of a randomized controlled trial.

  Yuki Arakawa, Kosuke Inoue, Maho Haseda, Daisuke Nishioka, Shiho Kino, Daisuke Nishi, Hideki Hashimoto, Naoki Kondo

  BACKGROUND: Although the short-term preventive effects of mHealth consultation intervention on postpartum depressive symptoms have been demonstrated, the long-term effects and role of alleviating loneliness on depressive symptoms remain unclear. METHODS: This follow-up study extended our previous trial, which ended at three months postpartum, by continuing observation to 12 months. Participants in the original trial were randomized to the mHealth group (n = 365) or the usual care group (n = 369). Women in the mHealth group had access to free, unlimited mHealth consultation services with healthcare professionals from enrollment through four months postpartum. The primary outcome of this study was the risk of elevated postpartum depressive symptoms at 12 months post-delivery (Edinburgh Postnatal Depression Scale score of ≥9). The mediation effect of alleviating loneliness on the primary outcome was also evaluated, using the UCLA loneliness scale at three months postpartum. RESULTS: A total of 515 women completed the follow-up questionnaires (mHealth group, 253/365; usual care group, 262/369; 70.2% of the original participants). Compared to the usual care group, the mHealth group had a lower risk of elevated postpartum depressive symptoms at 12 months post-delivery (36/253 [14.2%] vs. 55/262 [21.0%], risk ratio: 0.68 [95% confidence interval: 0.46-0.99]). Mediation analysis showed that reducing loneliness at three months post-delivery mediated approximately 20% of the total effect of the intervention on depressive symptoms 12 months post-delivery. CONCLUSIONS: mHealth consultation services provided during the early perinatal period may help alleviate depressive symptoms at 12 months postpartum.

• The difference in type 2 diabetes care between the National Health Insurance beneficiaries and public assistance recipients in Japan: A retrospective cohort study based on claims data in a municipality

  Takuya Yamaoka, Takehiro Sugiyama, Daisuke Nishioka, Naoki Kondo, Nanako Tamiya

  ABSTRACT Aims/Introduction We examined the differences in diabetes care between public assistance recipients (PARs), exempt from medical costs and guaranteed a minimum income, and the National Health Insurance (NHI) beneficiaries, covering non‐employed and self‐employed individuals with some cost sharing in Japan. Materials and Methods This observational study used claims data from a Japanese municipality (April 2017–March 2022) to identify individuals aged 20–68 with type 2 diabetes on antidiabetic medications. We analyzed care processes annually and cross‐sectionally, focusing on tests, medications, and medical costs, and followed health outcomes (hypoglycemia and hospitalization) monthly and longitudinally. Multivariable Poisson regression models estimate the risk ratios for binary care processes, and a gamma regression model analyzes medical costs as continuous variables. Health outcome incidence rate ratios were assessed using multivariable Poisson regression, with the observation period as an offset. Results We included cross‐sectional data from 11,385, 11,566, and 9,943 people (2018–2020) and longitudinal data from 18,655 individuals. In the analysis considering the whole periods, PARs were more likely to receive annual eye examinations (adjusted risk ratio 1.15, 95% confidence interval [CI] 1.08–1.22), use sodium‐glucose cotransporter‐2 inhibitors (1.22, 1.13–1.31), and use glucagon‐like peptide‐1 receptor agonists (1.63, 1.41–1.90). The total (1.16, 1.09–1.23) and outpatient medical costs (1.31, 1.24–1.38) were higher, whereas the inpatient costs (0.85, 0.77–0.94) were lower for PARs. Hypoglycemia incidence was also higher (adjusted incidence rate ratio 2.21, 95% CI 1.38–3.54). Conclusions Public assistance might improve the diabetes care process, but not fully health outcomes. These findings suggest additional supports for PARs and further research for NHI beneficiaries in poverty.

• [Reality of health and dietary support for public assistance recipients and individuals experiencing poverty].

  Saika Murohashi, Asami Ohta, Nobuko Murayama, Tatsuaki Sakamoto, Tomomi Kobayashi, Chika Horikawa, Daisuke Nishioka

  Objective Health support is important to promote independent living among individuals experiencing poverty who require welfare support. However, the actual state of the initiative and specific reality of the collaboration partners, within and outside the administration, remain unclear. The participants were welfare offices, which are the main implementers of the public assistance system, and social welfare councils, which are the main implementers of self-reliance consultations and support services for individuals experiencing poverty. This study aimed to clarify whether the health and dietary status of individuals receiving welfare support were checked at the initial interview and whether an assessment sheet was used to evaluate their health and dietary status. We aimed to confirm which organizations collaborate with and outside the government and clarify the content of dietary support.Methods In January 2024, we conducted a nationwide questionnaire survey of 1,250 welfare offices and 612 social welfare councils. We requested information regarding the confirmation of health and dietary status during the initial interview, use of assessment sheets, cooperation with other organizations, and implementation of dietary support.Results Of the welfare offices and social welfare councils, > 50% reported checking "physical condition," "regular visits to the hospital and medication," and "means of transportation" for health status during the initial interview with service recipients. They checked "frequency of eating out" and "meal frequency" for dietary status. Approximately 30% of patients in both groups had undergone medical examinations, and > 50% of the welfare offices did not use assessment sheets. The social welfare councils used assessment sheets but did not have any items to check dietary status. The multidisciplinary cooperation of welfare offices was in cooperation with the administration of health checkups and physicians. Social welfare councils cooperated with various organizations. The average number of cooperative groups was significantly higher among those who provided dietary advice in combination with food provision support, such as food banks. These groups were better informed about children's and community cafeterias than groups that did not provide such support.Conclusion To promote multilayered health and dietary support, assessment sheets could be beneficial for evaluating the health and dietary conditions of individuals requiring support, and cooperation with other organizations, including health professionals, may help create effective support networks.

  BACKGROUND: The optimal remission induction therapy for severe antineutrophil cytoplasmic antibody-associated vasculitis (AAV) remains unclear. This study evaluated the effectiveness of rituximab (RTX) as a remission induction therapy for severe AAV compared with intravenous cyclophosphamide (IVCY). METHODS: Patients with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) treated with systemic glucocorticoids (GCs) and IVCY or RTX as initial remission induction therapy in multicenter REVEAL study between 1991 and 2024 were enrolled. We compared efficacy and safety outcomes between the two groups. Effectiveness was evaluated using all-cause mortality, GC-remission rate, relapse rate, and end-stage renal disease (ESRD) progression rate. Safety was evaluated based on complications from severe infections. Inverse probability of treatment weighting (IPTW) was applied for selection bias. RESULTS: Of 555 patients with AAV, 178 with severe MPA or GPA were identified (IVCY group: N = 133, RTX group: N = 45). After adjustment by IPTW, no significant differences in baseline clinical characteristics were observed between them. The 10-year survival rate and GC-remission rate at 6 months were significantly higher in the RTX group (p = 0.04, p = 0.017, respectively). ESRD progression and relapse rates were comparable between two groups. Regarding safety, 15.2% of patients in the IVCY group died due to severe infections, whereas none did in the RTX group (p = 0.007). CONCLUSIONS: RTX demonstrated superior efficacy in improving survival and achieving GC remission, with fewer infection-related deaths compared to IVCY in patients with severe AAV. These findings reveal the efficacy and safety of RTX as a remission induction therapy in real-world Japanese clinical practice.

• Risk prediction model for relapse of anti-synthetase syndrome- associated interstitial lung disease in Japanese multicentre MYKO cohort study.

  Shogo Matsuda, Takuya Kotani, Katsumasa Oe, Daisuke Nishioka, Chifumi Akiyama, Mahiro Yamamoto, Takayasu Suzuka, Ran Nakashima, Hideaki Tsuji, Tsuneo Sasai, Yasuhiro Nohda, Tsuneyasu Yoshida, Yoichi Nakayama, Yuto Nakakubo, Atsubumi Ogawa, Kazuma Yoshida, Keisuke Hirobe, Yuki Aitani, Yudai Koshida, Hirofumi Miyake, Tohru Takeuchi

  OBJECTIVES: This study aimed to establish a risk prediction model for the relapse of anti-synthetase syndrome-associated interstitial lung disease (ASyS-ILD). METHODS: Patients diagnosed with ASyS-ILD and treated with prednisolone and calcineurin inhibitors as remission induction therapy were enrolled in the Japanese multicentre MYKO cohort. We followed up on patients who experienced relapse of ASyS-ILD after remission induction therapy, and examined the risk factors for predicting relapse by comparing initial clinical and laboratory findings. RESULTS: Of 487 patients diagnosed with idiopathic inflammatory myopathies between 1991 and 2024, 101 patients with ASyS-ILD were included. Tacrolimus was used by 81.2% of patients and 18.8% used ciclosporin as calcineurin inhibitors for a remission induction therapy. Thirty-nine patients (38.6%) relapsed ASyS-ILD during a median follow-up of 4.3 years, and 5-year relapse rate was 45.1%. Multivariate Cox regression analyses showed that the presence of acute/subacute ILD and a lower % forced vital capacity (FVC) on admission were independently identified as risk factors for relapse in patients with ASyS-ILD. Using the receiver operating curve analysis, %FVC ≤77% was determined as the cut-off levels for indicating a poor prognosis. The 5-year relapse rate was significantly higher in patients with acute/subacute ILD, % FVC ≤77% than in those without these parameters. A risk-prediction model (RPM) based on these parameters can stratify patients into low-, moderate-, and high-risk ILD relapse groups. CONCLUSION: Our multicentre cohort study showed that the RPM model using the presence of acute/subacute ILD and %FVC values was a useful tool for stratifying risk of ASyS-ILD relapse.

• Revisiting the Boot Flap for Secondary Repair of the Free Border in Cleft Lip

  Koichi Ueda, Yuka Hirota, Hiromi Kino, Chizuru Umeda, Daisuke Nishioka

  Background: Deficiency of the free border of the lip and “whistling lip” deformity are encountered in secondary repairs of unilateral and bilateral cleft lip. We have reported the use of the de-epithelialized oral vestibular flap (boot flap) for secondary cleft lip repair. We experienced more cases using this method and analyzed them. Methods: Fifty-nine patients with a cleft lip underwent secondary repair using this method. In unilateral cases, total scores were determined by evaluating the height of the notch, the volume of the upper lip tubercle, and the upper lip volume of the cleft side. In bilateral cases, total scores were determined by evaluating the height of the notch and the volume of the median lip tubercle. Results: Of the 46 patients with a unilateral cleft lip, 3 patients underwent a second boot flap operation due to undercorrection, and 1 patient underwent boot flap revision. Of the 12 patients with a bilateral cleft lip, 1 patient underwent a second boot flap operation due to flap atrophy. The second operation could be performed without any difficulty in either unilateral or bilateral cases. Compared with the preoperative scores, the postoperative scores improved significantly in both unilateral and bilateral cases. Conclusions: We experienced a recurrent notch deformity after direct suturing in a patient with a unilateral cleft lip. This was thought to be caused by scar contracture. To prevent a recurrent deformity, it is important to interrupt the plane where scar contracture occurs by incorporating a boot flap and augmenting the volume.

• Resolvin D1 improves bleomycin-induced alveolar maturation arrest in newborn rats

  Jun Shinohara, Tohru Ogihara, Shigeo Yamaoka, Yutaro Kawamura, Daisuke Nishioka, Kazumi Honda, Yumiko Yoshimura, Akira Ashida

  Abstract Sustained, non-resolving inflammation is a fundamental mechanism that causes bronchopulmonary dysplasia (BPD). Specialized pro-resolving mediators (SPMs) are attracting attention as the new endogenous anti-inflammatory agents because they facilitate only the resolution phase of inflammation without affecting its acute phase, indispensable for the elimination of noxious microorganisms and damaged tissues. The preventive effects of resolvin D1 (RvD1), an SPM, were analyzed using bleomycin (Bleo)-induced BPD model of neonatal rats. Starting from the postnatal day (PD)-0, Bleo and RvD1 were administered simultaneously. At PD-14, morphological and immunohistochemical analyses, and the expression of key genes suspected to be involved in the Bleo-induced lung damage, were examined. Bleo injection successfully recapitulated the pathological features of BPD, such as alveolar enlargement and simplification with septal thickening. RvD1 effectively inhibited such alveolar dysmorphogenesis with attenuating macrophage infiltration and restoring the arrested capillary growth. It significantly suppressed the Bleo-induced upregulation of insulin-like growth factor-1 (IGF-1), tenascin-C, elastin, and anillin. The changes in IGF-1 protein expression in the bronchial and alveolar epithelia were confirmed by immunostaining. RvD1 effectively improves Bleo-induced model of alveolar maturation arrest of BPD. The supplementation of SPMs including RvD1 seems to be a promising treatment for the infants with BPD.

• Sociodemographic determinants of dental care utilization among children receiving public assistance in Japan: a one-year observational study

  Daisuke Nishioka, Haruna Kawachi, Keiko Ueno, Shiho Kino, Jun Aida, Naoki Kondo

  Abstract Background Access to dental care for all children is a matter of human rights. While public assistance (PA) programs can potentially improve access to dental care through income support for daily living and healthcare services among children in low-income households, other social vulnerabilities influence access. We aimed to investigate the sociodemographic determinants of dental care access for children on PA in Japan. Methods This study included all children receiving PA benefits in six municipalities. We extracted sociodemographic data as of April 2016 on age, sex, single-parenthood, parents’ working status, nationality, presence of siblings, disability certificates, and timing of households’ PA receipt, and observed them for one year. Medical assistance claim data was used to identify children’s dental care use as the outcome. Cumulative incidence ratios (CIR) for each variable were calculated using multivariable modified Poisson regression analysis. Results Of the 1,990 children on PA, the mean age was 8.32 (standard deviation; 4.12), 998 (50.2%) were girls, 1256 (63.1%) lived in single-parent households, and 532 (26.7%) were born into households already receiving PA, and 1085 (54.5%) children accessed dental care. Children living in single-parent households had a higher dental care use (CIR: 1.12, 95% CI: 1.03–1.23) than those in non-single-parent households. Children born in PA households had a lower dental care use (CIR: 0.88, 95% CI: 0.79–0.98) than those who began receiving PA after birth. Conclusions Despite Japan’s comprehensive welfare PA system, dental care access barriers persist, particularly among children from non-single-parent households and those born into PA.

  As considering only the data of survey respondents overlooks the opinion of voiceless people, acknowledging the direction of response biases of social survey data is crucial. We aimed to examine the representativeness of social surveys among impoverished older individuals. We conducted a cross-sectional study. Using linkage data from the Japan Gerontological Evaluation Study (JAGES) and residential registry data of public assistance (PA), we examined the validity of responses on receiving PA, as documented by the JAGES. Furthermore, we assessed the sociodemographic factors associated with the response to the JAGES using information on age (65-74/75-84/≥85 years), sex (male/female), household composition (living alone or not), nationality (Japanese/others), and level of long-term care needs (not applicable/support required/care needed) using complete data of PA recipients. A multiple modified Poisson regression analysis was performed to calculate the adjusted incidence ratio (IR) for responses to each explanatory variable. Among the sampled 162 older PA recipients, 79 (48.8%) responded to the JAGES. Seven recipients were misclassified as non-recipients in JAGES survey. There was no misclassification among non-recipients. PA recipients living alone were more likely to respond to the JAGES (IR 1.48, 95% confidence interval, 1.02-2.13). Using linkage data of the PA and JAGES databases from different departments within the municipality, we observed that social survey data represented a greater proportion of individuals living alone than those living with others among older impoverished people. To provide equitable policies, stakeholders should collect further information on older impoverished individuals not living alone.

• The Reference Interval for the Attainment of Comparable Term Functional Levels of Pulmonary Oxygenation Capacity in Healthy Preterm Infants: A Single-Center Retrospective Study.

  Masako Yasui, Tohru Ogihara, Shigeo Yamaoka, Jun Shinohara, Yutaro Kawamura, Masamine Kijima, Yoshihiko Fukuda, Daisuke Nishioka, Yuri Ito, Akira Ashida

  OBJECTIVE: We aimed to identify the reference interval (RI) of the postmenstrual age (PMA) at which lung oxygenation capacity is sufficiently stable in healthy preterm infants. DESIGN AND SETTING: A single-center, retrospective study involving a cohort of infants born at gestational age (GA) < 34 weeks who were discharged without respiratory support and experienced no short-term adverse respiratory outcomes. OUTCOME MEASURES: The PMA when oxygen supplementation was discontinued (Stop-O2), and subsequent SpO2 stabilization at ≥ 96% with room air spontaneous breathing for three consecutive days (Stable-SpO2). RESULTS: Of the 243 eligible infants, 176 meeting the Stable-SpO2 criteria before discharge were analyzed. The upper limit of the RI (97.5th percentile) for Stop-O2 was 40.2 weeks PMA and that for Stable-SpO2 was 41.7. Limited to infants with GA < 30 weeks, the 97.5th percentile of Stop-O2 and Stable-SpO2 was 41.9 and 42.9 weeks PMA, respectively. When both indices plotted against GA were divided by K-means clustering, one distinct cluster straddled a wide range of GA with delayed achievement of Stop-O2 (39.6, median weeks PMA) or Stable-SpO2 (40.6). The SpO2 status when Stable-SpO2 criteria was fulfilled (mean SpO2, 97.3%; time spent with SpO2 > 90%, 97.7%) was nearly comparable to that of healthy term infants shortly after birth. CONCLUSIONS: The lung oxygenation capacity in most healthy preterm infants was near-term levels by 42 weeks PMA. Our data might be useful for determining the optimal timing for assessing respiratory function as well as the presence or absence of bronchopulmonary dysplasia in preterm infants.

• Successful or Uncomplicated Use of Drug-Coated Balloon Versus Drug-Eluting Stent Strategies for De Novo Culprit Lesions in Acute Coronary Syndromes: Insights from a Nationwide Registry in Japan.

  Tomonori Takahashi, Kyohei Yamaji, Shun Kohsaka, Hideki Ishii, Yuichiro Mori, Yuetsu Kikuta, Tetsuzo Wakatsuki, Koji Yamaguchi, Daisuke Nishioka, Kenya Kusunose, Tetsuya Amano, Masataka Sata, Ken Kozuma

  BACKGROUND: Randomized trials demonstrated that drug-coated balloon (DCB) was not inferior to drug-eluting stent (DES) for acute coronary syndrome (ACS). However, generalizability in clinical settings remains unclear. The present study compared the outcomes of DCB and DES strategies in percutaneous coronary intervention for ACS within a nationwide procedure-based registry. METHODS AND RESULTS: This was a retrospective analysis of a cohort study from a prospective, nationwide registry between January 2017 and December 2020 in Japan, focusing on patients with ACS who underwent DCB or DES for a single de novo lesion. Patients who required bailout stenting after treatment with DCB were excluded from the analysis. The 1-year incidence of all-cause mortality, cardiovascular death, noncardiovascular death, nonfatal ACS, stroke, and major bleeding events was compared. A subgroup analysis included lesion-based and ST-elevation myocardial infarction/non-ST-elevation ACS stratifications. Among 5212 propensity score-matched patients with ACS, no significant differences were observed in the 1-year incidence of all-cause mortality (4.5% versus 4.6%, hazard ratio [HR], 0.92 [95% CI, 0.72-1.19]); cardiovascular death (2.5% versus 2.5%, HR, 0.90 [95% CI, 0.64-1.26]); noncardiovascular death (2.0% versus 2.1%, HR, 0.96 [95% CI, 0.65-1.42]); or nonfatal ACS (1.7% versus 2.0%, HR, 1.04 [95% CI, 0.70-1.54]) between DCB and DES. DCB was associated with a higher incidence of stroke (0.8% versus 0.3%, HR, 2.33 [95% CI, 1.06-5.08]) and lower incidence of major bleeding events (1.4% versus 2.3%, HR, 0.65 [95% CI, 0.43-0.99]); however, these results were not reproduced in the subgroup analysis. CONCLUSIONS: The DCB strategy for successfully treated ACS cases achieved similar clinical outcomes to DES after 1 year. Further studies with an extended follow-up are needed to confirm these results.

• Current state and challenges of multidisciplinary collaboration by fire defense headquarters in Japan: A nationwide cross‐sectional survey

  Keiko Ueno, Daisuke Nishioka, Chie Teramoto

  Abstract Aim The role of emergency medical service personnel has recently shifted, necessitating fire defense headquarters to engage in multidisciplinary collaboration with community organizations. However, evidence of this collaboration is limited. This study aimed to investigate the current state and challenges of multidisciplinary collaboration between fire defense headquarters and long‐term care, welfare, and health organizations in the community. Methods A web‐based cross‐sectional survey was conducted in 2023 among fire defense headquarters in Japan to examine their collaboration with long‐term care, welfare, and health organizations, as well as the challenges encountered during collaboration. Descriptive statistics were used for numerical data, and a qualitative descriptive method was applied to text data. Results A total of 529 participants, constituting a response rate of 72.9%, were enrolled in this study. A total of 445 (84.1%) fire defense headquarters collaborated with long‐term care, welfare, and health organizations. The most common collaborating organizations were public health centers (62.5%), community comprehensive support centers (54.6%), and municipal departments of long‐term care (40.0%). Challenges of collaboration included “cannot contact organizations during nights and holidays” and “cannot obtain patient information from organizations due to privacy reasons.” Conclusion Fire defense headquarters and community organizations should continue fostering collaboration, addressing challenges, and adopting best practices, which will help define the role of fire defense headquarters within local collaborative frameworks.

• Public assistance program and food diversity among older people: a cross-sectional study using the Japan Gerontological Evaluation Study data

  Kotone Tanaka, Daisuke Nishioka, Atsushi Nakagomi, Keiko Ueno, Kazushige Ide, Shiho Kino, Nobuko Murayama, Katsunori Kondo

  Abstract Background Food diversity plays an important role in people’s healthy and affluent lives. However, poverty and eating alone can create multi-dimensional barriers to food diversity. Although public assistance programs guarantee a minimum income to people in need, financial support alone may not be sufficient to support the health of people in poverty. This study aimed to identify the differences in food diversity intake between older recipients of public assistance and non-recipients. Methods This cross-sectional study utilized data from the Japanese Gerontological Evaluation Study (2022), involving 14,467 participants aged 65 years and older. The Dietary Variety Score (DVS), ranging from 0 to 10 (higher scores indicate higher dietary variety), assessed dietary diversity based on the regular consumption of ten food groups. Receiving public assistance was categorized as “yes” or “no.” Eating together was defined as eating with others every day. To assess the relationship between receiving public assistance and the DVS, we calculated the unstandardized coefficient (β) and p values using a general linear model. Additionally, the interaction between public assistance and eating together was examined. As covariates, we adjusted for sociodemographic factors such as age, disease, marital status, and living alone. Results Men recipients of public assistance had a lower DVS, even after adjusting for sociodemographic factors (adjusted β: -0.72, p = 0.04). For women, no association was seen between receiving public assistance and a lower DVS (adjusted β: -0.19, p = 0.66). An interaction between public assistance and eating together was observed among men (p = 0.07). Conclusions Even after adjusting for sociodemographic factors, men recipients of public assistance have less food diversity than non-recipient men. Men recipients were more likely to increase their food diversity by eating together. To ensure recipients’ rights to food security, the public assistance program should provide additional support to integrate recipients into communities that enable them to eat together in addition to providing financial support.

• [Poverty status of households delinquent to paying school lunch fees: A descriptive study using the 2023 JACSIS study].

  Kotone Tanaka, Daisuke Nishioka, Yasutake Tomata, Takahiro Tabuchi

  Objective This study aimed to describe the living conditions of households that had experienced arrears in school lunch fees for economic reasons and compile basic data to devise measures to address the problem of arrears in school lunch fees and child poverty.Methods We used data from the JACSIS study (2023), focusing on households with at least one school-age child. A state of arrears in school lunch fees was defined as "experiencing arrears" if the participants reported that they had experienced being unable to pay their children's school lunch fees for financial reasons, and "not experiencing arrears" otherwise. We employed a set of indicators to evaluate the poverty and living conditions of guardians and children, such as deprivation, household income, changes in income, and food insecurity for household poverty status, and items related to adverse childhood experiences of guardians and children's living conditions. The number and percentage of respondents for each indicator were calculated by school lunch payment status.Results Of the 1,919 participants, 88 (4.6%) had experienced arrears in school lunch fees, while 1,831 (95.4%) had not. Among those who had experienced arrears, 97.7% were in a state of deprivation, compared to 9.1% of those who had not experienced arrears. Additionally, those who had experienced arrears had a higher percentage of households with an income of less than four million yen (10.0% without experience of arrears vs. 17.1% with experience), reduced income (48.4% vs. 85.2%), and higher food insecurity (11.2% vs. 26.1%). Children from households with arrears were more likely to be respond "I do not know" or "I do not want to answer" by their guardians on all items related to childhood adverse experiences. They were also more likely to have guardians with mental illness (7.4% vs. 27.3%) and to experience domestic violence (14.4% vs. 80.7%).Conclusion The findings suggest that households with school lunch fee arrears were likely to be experiencing severe poverty and situations suggestive of child maltreatment. Therefore, identifying arrears in school lunch fees as a sign of poverty may reduce the incidence of such arrears and help protect children's right to a healthy upbringing by connecting families to appropriate support.

• A data-driven approach to detect support strategies for children living in households receiving public assistance in Japan: a mixed methods study to establish tailor-made health and welfare care.

  Keiko Ueno, Daisuke Nishioka, Shiho Kino, Naoki Kondo

  BACKGROUND: Child poverty adversely affects children's health and social lives. Children in households receiving public assistance have diverse needs regarding their health and lives Therefore, they require tailored support interventions based on individual sociodemographic backgrounds and other personal attributes. However, to the best of our knowledge, no study has identified distinct segments of these children using self-reported data or evaluated the health and social support strategies for the obtained segments. This study aimed to apply a clustering technique to quantitatively identify the distinct segments among children in households receiving public assistance, qualitatively describe the segment characteristics, and suggest potentially effective health and social life support strategies for each segment. METHODS: In the quantitative phase, we used the probabilistic latent semantic analysis (PLSA), a machine learning-based soft clustering method, to identify the segments of children aged 10-15 years in households receiving public assistance. We used the segments obtained in the quantitative phase to subsequently conduct seven semi-structured interviews and one focus group with professionals supporting children with complex needs. The interviewees were asked to describe the segment characteristics and propose health and social life support strategies for each segment. RESULTS: In total, 1,275 children were included in the quantitative analysis. PLSA identified all the segments with distinct characteristics that made sense to professionals who supported children in households receiving public assistance, confirmed by qualitative findings: e.g. "children who can do things on their own" (Segment 1), "children living in a facility" (Segment 2), "children who are in hikikomori (social withdrawal)" (Segment 3), "children who cannot be bothered to answer conceptual questions about themselves" (Segment 4), and "children from households with intergenerational public assistance use" (Segment 5). The qualitative findings also suggested various support measures not only for physical health but also for the social and mental health of children in households receiving public assistance, for example, "financial support for higher education" for Segment 1, and "whole family support" for Segment 5. CONCLUSIONS: Children in households receiving public assistance can be categorized into distinct segments and would consequently benefit from tailored support strategies for their health and social lives.

• Characteristics and hospitalizations among children on public assistance in Japan: A population‐based cohort study

  Daisuke Nishioka, Keiko Ueno, Shiho Kino, Naoki Kondo

  BACKGROUND: Child poverty is a critical issue in Japan. While public assistance (seikatsu-hogo) alleviates financial barriers to healthcare, the multidimensional nature of poverty, including social and environmental factors, may still affect children's health. Although previous research has explored health disparities among adults receiving public assistance, little is known about the current conditions and healthcare needs of child recipients. This study aimed to describe the characteristics of children on public assistance and identify the incidence and predictors of hospitalization among them. METHODS: This retrospective cohort study included children receiving public assistance in six Japanese municipalities. We extracted data on children's age, sex, household composition, siblings, guardians' employment status, timing of public assistance receipt, nationality, and disability certificates as of April 2016 and observed them for 1 year. The primary outcome was all-cause hospitalization. Poisson regression analyses were performed to identify predictors of hospitalization. RESULTS: We analyzed data from 1990 children receiving public assistance. Overall, 4.6% were hospitalized during the observation period, with higher rates in younger children and those with disabilities. Hospitalization incidence was varied across households conditions and residing municipalities. CONCLUSIONS: Children on public assistance in Japan may face higher hospitalization risks, and the differences were observed across household conditions and residential areas. Further research using more detailed data should explore child poverty and health, including both recipients and non-recipients of public assistance.

  BACKGROUND: This study investigated poor prognostic factors for the relapse of interstitial lung disease (ILD) in patients with microscopic polyangiitis (MPA) after remission induction therapy. METHODS: We enrolled patients diagnosed with MPA complicated by ILD according to the Chapel Hill Consensus definition from 2001 to 2023 in multiple institutions in the REVEAL cohort. All patients who were treated with immunosuppressive therapy were followed up, and those who relapsed with ILD were extracted in this study. We explored the risk factors for predicting ILD relapse in patients with MPA-ILD by comparing the demographic, clinical, laboratory, and radiological findings and treatments between the relapsed and non-relapsed groups on admission. RESULTS: Of 243 patients with MPA, 134 (55.1%) with MPA-ILD were enrolled. Among them, 28 (20.9%) relapsed during a mean follow-up of 4.2 years. The initial serum Krebs von den Lungen-6 (KL-6) and surfactant protein-D (SP-D) levels and the prevalence of usual interstitial pneumonia (UIP) pattern were significantly higher in the relapsed group. The biomarkers were also risk factors for relapse in multivariate Cox regression analysis. The best cut-off values of KL-6, SP-D for predicting ILD relapse were 430 U/mL and 89.5 ng/mL, respectively. We created prediction models based on the best cut-off values for KL-6, SP-D, and the presence of the UIP pattern (KSU model). The 10-year relapse rate was significantly different among patients with MPA-ILD stratified by the number of risk factors based on the KSU model. A higher relapse rate was associated with higher all-cause mortality. CONCLUSIONS: The initial serum high KL-6 and SP-D levels and the prevalence of the UIP pattern were associated with ILD relapse in patients with MPA-ILD. Our multicentre cohort study indicated that the KSU model, which consists of KL-6 ≥ 430 U/mL, SP-D ≥ 89.5 ng/mL, and the presence of the UIP pattern, is a useful predictor of ILD relapse in patients with MPA after immunosuppressive therapy.

• [Telephone navigation and health check attendance among public assistance recipients: Lessons from two-year effort in Toyonaka City].

  Daisuke Nishioka, Shoko Takemoto

  Objective Poverty is a significant health determinant. As public assistance recipients experience difficulties in health management, a healthcare management support program to provide health checks has been implemented by welfare offices in Japan since 2021. However, effective approaches to maximize health check rates are limited. This study aimed to identify the impact of telephone navigation on recipients' health check-receiving behaviors, using data from welfare offices in Toyonaka City.Methods This study included recipients aged 40-60 years who received telephone navigation for health check programs in 2021 and 2022. In 2021, telephone navigation was provided to eligible recipients. In 2022, the recipients were divided into two groups based on their household identification numbers (even/odd). We examined the difference in the health check rate in 2021 depending on whether the navigation system was connected. Additionally, we examined the differences across groups and navigation periods in 2022.Results In 2021, 32 (7.9%) recipients received health checks. Twenty-six (10.2%) of the 255 recipients and six (4.1%) of the 148 recipients in the navigated and non-navigated groups, respectively, underwent health checks. In the navigated group, health check rates were higher among recipients in their 50s (13.3% vs. 3.1%; P = 0.006), unemployed recipients (13.9% vs. 3.6%; P = 0.014), those who did not receive previous health checks (9.1% vs. 1.5%; P = 0.003), and those who did not receive regular medical consultations (8.3% vs. 0%; P = 0.012). In 2022, 247 and 225 patients were assigned to the odd- and even-numbered groups, respectively, with no differences in their characteristics. During the intervention period, four (1.6%) of the 247 recipients and 10 (4.6%) of the 219 recipients in the odd- and even-numbered groups, respectively, underwent health checks. During the non-intervention period, five (2.1%) and six (2.7%) recipients of the odd- and even-numbered groups, respectively, underwent health checks. Health check rates were higher toward the deadlines. The estimated conditional odds ratio for receiving the health checks by the navigation was 1.35 (95% confidence interval; 0.59-2.93, P = 0.503).Conclusion Telephone navigation may be effective in some recipients. Meanwhile, targeting recipients with attributes, such as "in their 50s," "unemployed," "received no previous health checks," and "received no regular medical consultations" may increase the response rate. Therefore, policymakers should consider using reliable telephone navigation methods and navigating near deadlines.

• Understanding the daily life needs of older public assistance recipient subgroups in Japan: A qualitative study.

  Keiko Ueno, Daisuke Nishioka, Junko Saito, Shiho Kino, Naoki Kondo

  Transition from individual-level treatment to social-level intervention should be made to improve peoples daily living conditions for reducing health inequality, which is a major global public health concern. Older public assistance recipients in Japan are socially vulnerable and require healthcare, long-term care, daily living, and social care support. Understanding the diverse daily living needs among public assistance recipient subgroups would prompt the development of novel support measures in the welfare sector. Therefore, this study aimed to understand the daily life needs of older recipient subgroups (segments) created quantitatively in our previous study. We interviewed four caseworkers at municipal welfare offices in 2021; the interview data were analyzed using a qualitative descriptive method to describe the daily life needs of the five older recipient segments for each sex. Five themes of daily life needs were demonstrated: i) housing, ii) financial, iii) welfare service, iv) healthcare, and v) no daily life needs. Consequently, we identified the daily life needs of some older recipient segments, indicating the necessity for support interventions. Future research would help interview other professionals from various backgrounds to further understand the daily life needs of older recipient segments.

• Risk factors and outcome of hyponatremia in patients with Guillain-Barré syndrome.

  Shoji Ogawa, Takafumi Hosokawa, Chizuko Hayakawa, Taiki Sawai, Kensuke Kakiuchi, Daisuke Nishioka, Yukiyo Yoshimoto, Yuichi Masuda, Yoshitsugu Nakamura, Shin Ota, Shigeki Arawaka

  The objective of the present study was to evaluate the risk factors and outcomes associated with hyponatremia in patients with Guillain-Barré syndrome (GBS). We retrospectively studied 80 consecutive patients with GBS who visited our hospital and compared clinical, laboratory, and electrophysiological findings of patients with and without hyponatremia. Disability was evaluated using the Hughes grading system. Of the 80 patients, 18 (23%) had hyponatremia. Hyponatremia was significantly associated with older age (P = 0.003), urinary retention (P < 0.0001), Hughes grade ≥ 4 at admission and nadir (P = 0.003 and P < 0.001, respectively), acute inflammatory demyelinating polyneuropathy subtype (P = 0.017), sepsis (P = 0.001), mechanical ventilator support (P = 0.013), longer hospitalization length of stay (P < 0.0001), and inability to walk independently at 6 months (P < 0.001). Multivariate analysis performed to assess the risk factors of hyponatremia revealed that urinary retention (odds ratio [OR] 30.7, 95% confidence interval [CI] 3.6-264.4; P = 0.002) and mechanical ventilator support (OR 13.8, 95% CI 1.6-118.0; P = 0.017) were significant independent risk factors of hyponatremia. In assessing the outcomes of patients with hyponatremia, multivariate analysis showed that hyponatremia was independently associated with hospitalization length of stay ≥ 60 days and inability to walk independently at 6 month, with the former showing statistical significance but the latter not (OR 9.3, 95% CI 1.8-47.7; P = 0.007 and OR 4.9, 95% CI 0.9-26.3; P = 0.066, respectively). Therefore, we demonstrate that, along with mechanical ventilator support, urinary retention-possibly indicating autonomic dysfunction-is a risk factor of hyponatremia in GBS. Moreover, we confirm that hyponatremia is associated with poor outcome in GBS.

• Health Statuses of People in Poverty Receiving Public Assistance in Japan: A Scoping Review.

  Haruna Kawachi, Daisuke Nishioka

  BACKGROUND: Promoting health and well-being is essential to ensure dignified lives of the entire population, including those living in poverty. Guaranteeing the human right to health is a critical responsibility of social security policies. To address emerging issues associated with poverty, the Japanese government has implemented a welfare program known as public assistance-seikatsu-hogo. However, financial welfare programs may not fully mitigate health risks due to the complex impact of poverty on health. Although a global systematic review of the health status of public and social assistance recipients has been conducted, it did not include any studies from Japan. Furthermore, evidence for the development of health support strategies for Japanese recipients remains scarce. This scoping review aims to identify the current situation and potential issues concerning the health of recipients. METHODS: PubMed was searched for articles published before November 2023. Of the 357 articles identified, 56 were included. Among those included, 35 used the individual status of receiving public assistance as an exposure variable, 13 considered public assistance recipients as the study population, and 8 used the prefectural proportion of the population receiving public assistance as an environmental predictor. RESULTS: We found that public assistance recipients tend to have more disadvantageous health and well-being statuses than the general population, as reported in the global systematic review. Health inequalities were also observed among recipients based on their sociodemographic characteristics. In Japan, public assistance recipients face several health risks and are at a disadvantage compared with the general population. CONCLUSIONS: The distribution of risks is heterogeneous among recipients, despite the minimum income protection and financial benefits in health and long-term care use. Further studies to identify the effects of public assistance policy on the health of the impoverished population, evidence-based discussions, and reform of social security policies are warranted.

  Ryo Horiike, Tomoya Itatani, Hisao Nakai, Daisuke Nishioka, Aoi Kataoka, Yuri Ito

  INTRODUCTION: This study evaluated the detection of monthly human mobility clusters and characteristics of cluster areas before the coronavirus disease 2019 (COVID-19) outbreak using spatial epidemiological methods, namely, spatial scan statistics and geographic information systems (GIS). METHODS: The research area covers approximately 10.3 km2, with a population of about 350,000 people. Analysis was conducted using open data, with the exception of one dataset. Human mobility and population data were used on a 1-km mesh scale, and business location data were used to examine the area characteristics. Data from January to December 2019 were utilized to detect human mobility clusters before the COVID-19 pandemic. Spatial scan statistics were performed using SaTScan to calculate relative risk (RR). The detected clusters and other data were visualized in QGIS to explore the features of the cluster areas. RESULTS: Spatial scan statistics identified 33 clusters. The detailed analysis focused on clusters with an RR exceeding 1.5. Meshes with an RR over 1.5 included one with clusters for 1 year which is identified in all months of the year, one with clusters for 9 months, three with clusters for 6 months, three with clusters for 3 months, and four with clusters for 1 month. September had the highest number of clusters (eight), followed by April and November (seven each). The remaining months had five or six clusters. Characteristically, the cluster areas included the vicinity of railway stations, densely populated business areas, ball game fields, and large-scale construction sites. CONCLUSIONS: Statistical analysis of human mobility clusters using open data and open-source tools is crucial for the advancement of evidence-based policymaking based on scientific facts, not only for novel infectious diseases but also for existing ones, such as influenza.

• Diabetes control in public assistance recipients and free/low-cost medical care program beneficiaries in Japan: a retrospective cross-sectional study

  Mitsuhiko Funakoshi, Daisuke Nishioka, Seiji Haruguchi, Sakae Yonemura, Takashi Takebe, Misato Nonaka, Sanae Iwashita

  Introduction Previous research has highlighted the association between socioeconomic factors and diabetes management. This study aimed to elucidate the blood glucose control status among individuals with low income (ie, recipients of public assistance (PARs) and free/low-cost medical care (FLCMC) programme beneficiaries) and to investigate the effects of public subsidies for medical expenses on treatment adherence among low-income patients with diabetes. Methods We conducted a secondary analysis of medical records from 910 outpatients with diabetes who underwent pharmacological treatment for >90 days. Data on predictive variables, such as glycated haemoglobin (HbA1c) level and control variables, including sex, age and insurance type, were obtained retrospectively. The HbA1c levels among public health insurance (PHI)-only beneficiaries, FLCMC programme beneficiaries and PARs were compared using logistic regression analysis. Results The analysis included 874 individuals, among whom the majority were men (61.7%) and aged≥65 years (58.4%). Logistic regression analysis revealed that among individuals aged ˂65 years, the adjusted ORs for HbA1c levels above 9% were significantly higher in FLCMC programme beneficiaries (OR=5.37, 95% CI: 2.23 to 12.82) and PARs (OR=5.97, 95% CI: 2.91 to 12.74) than in PHI-only beneficiaries. Among patients aged ˂65 years with HbA1c levels above 7%, the adjusted OR was significantly higher in FLCMC programme beneficiaries (OR=3.82, 95% CI: 1.65 to 10.43) than in PHI-only beneficiaries. Additionally, the adjusted OR was significantly higher in FLCMC programme beneficiaries aged ˂65 years (OR=2.57, 95% CI: 1.02 to 7.44) than in PARs. Conclusions This study highlights the predictive value of public assistance or the FLCMC programme for poor blood glucose control and suggests the inadequacy of current medical expense subsidies to eliminate health disparities in diabetes control.

  Abstract Background Endoscopic mucosal healing serves as a critical predictor for achieving long-term remission in Crohn’s disease treatment. Recent data indicate that the effectiveness of healing varies based on the location of gastrointestinal inflammation. Additionally, reports are suggesting that anti-tumor necrosis factor-α (anti-TNF-α) agents exhibit reduced efficacy in treating small intestinal inflammation compared to colorectal inflammation. Conversely, limited research exists regarding the impact of the anti-IL12/23 agent ustekinumab (UST) on small intestinal inflammation. This study aimed to compare the effects of anti-TNF-α agents and ustekinumab on small intestinal inflammation using propensity score analysis. Methods This retrospective observational study involved 70 patients with Crohn’s disease who had inflammation in the small intestine and had initiated treatment with either anti-TNF agents or ustekinumab between March 2015 and August 2021. Endoscopic findings were evaluated before treatment commencement and at 1–2 years post-treatment initiation. The propensity score was employed to compare the efficacy of TNF agents and ustekinumab on small bowel inflammation. Results Ustekinumab exhibited greater improvement in the small intestinal endoscopy score than anti-TNF-α antibodies according to the propensity score analysis (inverse probability weighting) (p = 0.0448). However, no significant disparity was observed in the overall improvement of endoscopic scores between ustekinumab and anti-TNF-α antibodies (p = 0.5938). Conclusions This study suggests that ustekinumab might be more effective than anti-TNF-α agents in treating small intestinal inflammation in Crohn’s disease.

• Factors associated with prolonged on-scene time in ambulance transportation among patients with minor diseases or injuries in Japan: a population-based observational study.

  Keiko Ueno, Chie Teramoto, Daisuke Nishioka, Shiho Kino, Hiroyuki Sawatari, Kazuaki Tanabe

  BACKGROUND: Prolonged prehospital time is a major global problem in the emergency medical system (EMS). Although factors related to prolonged on-scene times (OSTs) have been reported in patients with trauma and critical medical conditions, those in patients with minor diseases or injuries remain unclear. We examined factors associated with prolonged OSTs in patients with minor diseases or injuries. METHODS: This population-based observational study used the ambulance transportation and request call record databases of the Higashihiroshima Fire Department, Japan, between January 1, 2016, and December 31, 2022. The participants were patients with minor diseases or injuries during the study period. We performed a multivariable logistic regression analysis with robust error variance to examine the association between patient age, sex, severity, accident type, date and time of ambulance call, and the coronavirus disease 2019 (COVID-19) pandemic with prolonged OSTs. Prolonged OST was defined as ≥ 30 min from the ambulance arrival at the scene to departure. RESULTS: Of the 60,309 people transported by ambulance during the study period, 20,069 with minor diseases or injuries were included in the analysis. A total of 1,241 patients (6.2%) experienced prolonged OSTs. Fire accidents (adjusted odds ratio [aOR]: 7.77, 95% confidence interval [CI]: 3.82-15.79), natural disasters (aOR: 28.52, 95% CI: 2.09-389.76), motor vehicle accidents (aOR: 1.63, 95% CI: 1.30-2.06), assaults (aOR: 2.91, 95% CI: 1.86-4.53), self-injuries (aOR: 5.60, 95% CI: 3.37-9.32), number of hospital inquiries ≥ 4 (aOR: 77.34, 95% CI: 53.55-111.69), and the COVID-19 pandemic (aOR: 2.01, 95% CI: 1.62-2.50) were associated with prolonged OSTs. Moreover, older and female patients had prolonged OSTs (aOR: 1.18, 95% CI: 1.01-1.36 and aOR: 1.12, 95% CI: 1.08-1.18, respectively). CONCLUSIONS: Older age, female sex, fire accidents, natural disasters, motor vehicle accidents, assaults, self-injuries, number of hospital inquiries ≥ 4, and the COVID-19 pandemic influenced prolonged OSTs among patients with minor diseases or injuries. To improve community EMS, we should reconsider how to intervene with potentially modifiable factors, such as EMS personnel performance, the impact of the presence of allied services, hospital patient acceptance systems, and cooperation between general emergency and psychiatric hospitals.

  Abstract Background We aimed to determine whether puncture sites for blood sampling and topical disinfectants are associated with rates of contaminated blood cultures in the emergency department (ED) of a single institution. Methods This single‐center, ambidirectional cohort study of 548 consecutive patients ≥20 years of age was performed in the ED of a university hospital in Japan over a 13‐month period. Pairs of blood samples were collected for aerobic and anaerobic cultures from patients in the ED. Physicians selected puncture sites and topical disinfectants according to their personal preference. Results Potential contamination was identified in 110 of the 548 patients (20.1%). One hundred fourteen (20.8%) patients showed true‐positive results for bacteremia, and 324 (59.1%) patients showed true‐negative results. Multivariate analysis revealed more frequent contamination when puncture sites were disinfected with povidone‐iodine (PVI) than with alcohol/chlorhexidine (ACHX) (adjusted risk difference, 19.1%; 95% confidence interval [CI]), 15.7–22.6; p < 0.001). In terms of blood collection sites, femoral and central venous (CV) catheter with PVI disinfection showed more frequent contamination than venous sites with ACHX (adjusted risk differences: 26.6%, 95% CI 21.3–31.9, p < 0.001 and 41.1%, 95% CI 22.2–59.9, p < 0.001, respectively). Conclusion Rates of contaminated blood cultures were significantly higher when blood was collected from the CV catheter or femoral sites with PVI as the topical disinfectant.

  Abstract Background To establish refined risk prediction models for mortality in patients with microscopic polyangiitis (MPA) by using comprehensive clinical characteristics. Methods Data from the multicentre Japanese registry of patients with vasculitis (REVEAL cohort) were used in our analysis. In total, 194 patients with newly diagnosed MPA were included, and baseline demographic, clinical, laboratory, and treatment details were collected. Univariate and multivariate analyses were conducted to identify the significant risk factors predictive of mortality. Results Over a median follow-up of 202.5 (84–352) weeks, 60 (30.9%) of 194 patients died. The causes of death included MPA-related vasculitis (18.3%), infection (50.0%), and others (31.7%). Deceased patients were older (median age 76.2 years) than survivors (72.3 years) (P < 0.0001). The death group had shorter observation periods (median 128.5 [35.3–248] weeks) than the survivor group (229 [112–392] weeks). Compared to survivors, the death group exhibited a higher smoking index, lower serum albumin levels, higher serum C-reactive protein levels, higher Birmingham Vasculitis Activity Score (BVAS), higher Five-Factor Score, and a more severe European Vasculitis Study Group (EUVAS) categorization system. Multivariate analysis revealed that higher BVAS and severe EUVAS independently predicted mortality. Kaplan–Meier survival curves demonstrated lower survival rates for BVAS ≥20 and severe EUVAS, and a risk prediction model (RPM) based on these stratified patients into low, moderate, and high-risk mortality groups. Conclusions The developed RPM is promising to predict mortality in patients with MPA and provides clinicians with a valuable tool for risk assessment and informed clinical decision-making.

• Sociodemographic inequities in unscheduled asthma care visits among public assistance recipients in Japan: additional risk by household composition among workers

  Daisuke Nishioka, Junko Saito, Keiko Ueno, Naoki Kondo

  Abstract Background Public assistance programs aim to prevent financial poverty by guaranteeing a minimum income for basic needs, including medical care. However, time poverty also matters, especially in the medical care adherence of people with chronic diseases. This study aimed to examine the association between the dual burden of working and household responsibilities, with unscheduled asthma care visits among public assistance recipients in Japan. Methods This retrospective cohort study included public assistance recipients from two municipalities. We obtained participants’ sociodemographic data in January 2016 from the public assistance database and identified the incidence of asthma care visits. Participants’ unscheduled asthma visits and the frequency of asthma visits were used as the outcome variables. Unscheduled visits were defined as visits by recipients who did not receive asthma care during the first three months of the observation period. Participants’ age, sex, household composition, and work status were used as explanatory variables. Multiple Poisson regression analyses were performed to calculate the cumulative incidence ratio (IR) with a 95% confidence interval (CI) of unscheduled visits across the explanatory variables. The effect of modification on the work status by household composition was also examined. Results We identified 2,386 recipients at risk of having unscheduled visits, among which 121 patients (5.1%) had unscheduled visits. The multivariable Poisson regression revealed that the working recipients had a higher incidence of unscheduled visits than the non-working recipients (IR 1.44, 95% CI 1.00–2.07). Among working recipients, the IRs of unscheduled visits were higher among recipients cohabiting with adults (IR 1.90 95% CI 1.00–3.59) and with children (IR 2.35, 95% CI 1.11–4.95) than for recipients living alone. Among non-working recipients, the IRs of unscheduled visits were lower for recipients living with family (IR 0.74, 95% CI 0.41–1.35) and those living with children (IR 0.50, 95% CI 0.20–1.23). A higher frequency in asthma visits was observed among working recipients living with family. Conclusions Working adults cohabiting with children are at the greatest risk of unscheduled visits among adults receiving public assistance. To support healthy lifestyles of public assistance recipients, medical care providers and policymakers should pay special attention to the potentially underserved populations.

  Abstract Background The COVID-19 pandemic substantially magnified the inequity gaps among vulnerable populations. Both public health (PH) and primary health care (PHC) have been crucial in addressing the challenges posed by the pandemic, especially in the area of vulnerable populations. However, little is known about the intersection between PH and PHC as a strategy to mitigate the inequity gap. This study aims to assess the collaboration between PHC and PH with a focus on addressing the health needs of vulnerable populations during the COVID-19 pandemic across jurisdictions. Methods We analyzed and compared data from jurisdictional reports of COVID-19 pandemic responses in PHC and PH in Belgium, Canada (Ontario), Germany, Italy, Japan, the Netherlands, Norway, and Spain from 2020 to 2021. Results Four themes emerge from the analysis: (1) the majority of the countries implemented outreach strategies targeting vulnerable groups as a means to ensure continued access to PHC; (2) digital assessment in PHC was found to be present across all the countries; (3) PHC was insufficiently represented at the decision-making level; (4) there is a lack of clear communication channels between PH and PHC in all the countries. Conclusions This study identified opportunities for collaboration between PHC and PH to reduce inequity gaps and to improve population health, focusing on vulnerable populations. The COVID-19 response in these eight countries has demonstrated the importance of an integrated PHC system. Consequently, the development of effective strategies for responding to and planning for pandemics should take into account the social determinants of health in order to mitigate the unequal impact of COVID-19. Careful, intentional coordination between PH and PHC should be established in normal times as a basis for effective response during future public health emergencies. The pandemic has provided significant insights on how to strengthen health systems and provide universal access to healthcare by fostering stronger connections between PH and PHC.

• Prediction model for respiratory-related mortality in microscopic polyangiitis with interstitial lung disease: multicentre REVEAL cohort study

  Shogo Matsuda, Takuya Kotani, Ayana Okazaki, Daisuke Nishioka, Ryu Watanabe, Takaho Gon, Atsushi Manabe, Mikihito Shoji, Keiichiro Kadoba, Ryosuke Hiwa, Wataru Yamamoto, Motomu Hashimoto, Tohru Takeuchi

  Abstract Objective This study aimed to establish prediction models for respiratory-related mortality in microscopic polyangiitis (MPA) complicated by interstitial lung disease (ILD) using clinical characteristics. Methods We enrolled patients with MPA with ILD between May 2005 and June 2021 in a multicentre cohort of Japanese patients with MPA (REVEAL cohort). We evaluated the demographic, clinical, laboratory, radiological findings, treatments and the presence of honeycombing 1 cm above the diaphragm using chest high-resolution CT (HRCT) on admission. We explored the risk factors predictive of respiratory-related mortality. Results Of 115 patients, 26 cases died of respiratory-related diseases during a median follow-up of 3.8 years. Eighteen patients (69%) died due to respiratory infection, three (12%) had diffuse alveolar haemorrhage, and five (19%) had exacerbation of ILD. In univariate analysis, older age, lower percent forced vital capacity (%FVC), lower percent diffusing capacity of carbon monoxide (%DLCO), and the presence of honeycombing in the right lower lobe were identified as risk factors. Additionally, in multivariate analysis adjusted for age and treatment, %FVC, %DLCO and the presence of honeycombing in the right lower lobe were independently associated with respiratory-related mortality. We created prediction models based on the values of %FVC, %DLCO and presence of honeycombing on chest HRCT (termed “MPF model”). The 5-year respiratory-related death-free rate was significantly different between patients with MPA with ILD stratified by the number of risk factors based on the MPF model. Conclusions Our study indicates that the MPF model may help predict respiratory-related death in patients with MPA with ILD.

• Prevalence of dental visits in older Japanese adults receiving public assistance

  Shiho Kino, Keiko Ueno, Daisuke Nishioka, Naoki Kondo, Jun Aida

  Abstract Objectives Exemption from paying dental care costs among recipients of public assistance contributes to universal health care coverage. Although this system might reduce the financial barriers to dental care among patients, there are still several other barriers for public assistance recipients. Therefore, this study examined whether receiving public assistance was associated with a higher prevalence of dental visits for any reason, treatment and prevention. Methods Data were obtained from 16 366 respondents from the 2019 wave of a nationwide cohort study on older adults in Japan. Poisson regression analyses with robust error variance were used to examine the associations between receiving public assistance and dental visits, adjusting for number of teeth, dental pain, periodontal conditions, age, sex, number of family members, education, equivalent household income, working status, instrumental activities of daily living, medical conditions, depressive symptoms, instrumental support and geographical variations. Results More than half of the non‐recipients of public assistance visited a dentist for some reason in the past 6 months. Meanwhile, only 37% of the recipients visited a dentist. In addition, almost half of the non‐recipients had treatment visits, while only 34% of the recipients visited. Furthermore, 46% of the non‐recipients had dental visits for prevention, while 32% of the recipients had preventive visits. In the fully adjusted models, compared to non‐recipients, public assistance recipients were 24% (Prevalence Ratio [PR]: 0.76, 95% Confidence Intervals [CI]: 0.64, 0.90), 23% (PR: 0.77, 95% CI: 0.65, 0.92) and 21% (PR: 0.79, 95% CI: 0.65, 0.95) less likely to have dental visits for any reason, treatment, and prevention, respectively. Conclusions Although recipients were exempted from dental treatment fees, receiving public assistance was associated with a lower prevalence of dental visits for any reason, treatment and prevention. Future studies should identify the barriers to accessing dental care among public assistance recipients to improve dental visits.

• Identifying meaningful subpopulation segments among older public assistance recipients: a mixed methods study to develop tailor-made health and welfare interventions

  Keiko Ueno, Daisuke Nishioka, Junko Saito, Shiho Kino, Naoki Kondo

  Abstract Background Public assistance recipients have diverse and complex needs for health and social support in addition to financial support. Segmentation, which means dividing the population into subgroups (segments) with similar sociodemographic characteristics, is a useful approach for allocating support resources to the targeted segments. Clustering is a commonly used statistical method of segmentation in a data-driven marketing approach. This explanatory sequential mixed methods study applied a clustering technique, aiming to identify segments among older public assistance recipients quantitatively, and assess the meaningfulness of the identified segments in consultation and support activities for older recipients qualitatively. Methods We identified the segments of older recipients in two municipalities using probabilistic latent semantic analysis, a machine learning-based soft clustering method. Semi-structured interviews were subsequently conducted with caseworkers to ask whether the identified segments could be meaningful for them in practice and to provide a reason if they could not think of any older recipients from the segment. Results A total of 3,165 older people on public assistance were included in the analysis. Five distinct segments of older recipients were identified for each sex from 1,483 men and 1,682 women. The qualitative findings suggested most of identified segments reflected older recipients in practice, especially two of them: female Cluster 1 (facility residents aged over 85 years with disability/psychiatric disorder), and female Cluster 2 (workers). Some caseworkers, however, did not recall older recipients in practice when working with certain segments. Conclusions A clustering technique can be useful to identify the meaningful segments among older recipients and can potentially discover previously unrecognized segments that may not emerge through regular consultation practices followed by caseworkers. Future research should investigate whether tailored support interventions for these identified segments are effective.

• Remote Communication and Loneliness During the COVID-19 Pandemic: Cross-Sectional Study

  Yuki Arakawa, Kosuke Inoue, Daisuke Nishioka, Atsushi Nakagomi, Takahiro Tabuchi, Naoki Kondo

  Background Although remote communication technologies have been widely used to maintain connections with others against interpersonal contact restrictions and exacerbated loneliness during the COVID-19 pandemic, it is unclear whether and what types of remote communication technologies are effective in mitigating loneliness. Objective This study aimed to investigate the association between remote communication and loneliness when face-to-face meetings with others were strongly prohibited and whether this association varied across types of communication tools, age, and gender. Methods We used cross-sectional data from the Japan COVID-19 and Society Internet Survey conducted from August to September 2020. From registered panelists of the research agency, 28,000 randomly sampled participants completed the survey on the website. We created 2 study cohorts who stopped meeting with family members living apart and friends during the pandemic. We categorized whether participants had technology-based remote communication (voice calling, text messaging, and video calling) with family and friends. Loneliness was assessed using the 3-item University of California, Los Angeles Loneliness Scale. We used a modified Poisson regression model to investigate the association between loneliness and remote communication with family members living apart or friends. We also conducted subgroup analyses based on age and gender. Results A total of 4483 participants stopped meeting with family members living apart, and 6783 participants stopped meeting with friends during the COVID-19 pandemic. Remote communication with family members living apart did not show an association with loneliness, whereas remote communication with friends was associated with a low prevalence of loneliness (family: adjusted prevalence ratio [aPR]=0.89, 95% CI 0.74-1.08; P=.24 and friends: aPR=0.82, 95% CI 0.73-0.91; P<.001). From analyses by tools, voice calling was associated with low loneliness (family: aPR=0.88, 95% CI 0.78-0.98; P=.03 and friends: aPR=0.87, 95% CI 0.80-0.95; P=.003). Similarly, text messaging was associated with low loneliness (family: aPR=0.82, 95% CI 0.69-0.97; P=.02 and friends: aPR=0.81, 95% CI 0.73-0.89; P<.001). However, we did not find an association between video calling and loneliness (family: aPR=0.88, 95% CI 0.75-1.02; P=.09 and friends: aPR=0.94, 95% CI 0.85-1.04; P=.25). Text messaging with friends was associated with low loneliness regardless of age, whereas voice calling with family or friends was associated with low loneliness only among participants aged ≥65 years. An association between remote communication with friends and low loneliness was found regardless of the type of remote communication tool among men, whereas it was found only for text messaging with friends among women. Conclusions In this cross-sectional study of adults in Japan, remote communication, especially via voice calling and text messaging, was associated with low loneliness. Promoting remote communication may reduce loneliness when face-to-face contact is restricted, which should be the subject of future research.

• Effectiveness of mHealth consultation services for preventing postpartum depressive symptoms: a randomized clinical trial

  Yuki Arakawa, Maho Haseda, Kosuke Inoue, Daisuke Nishioka, Shiho Kino, Daisuke Nishi, Hideki Hashimoto, Naoki Kondo

  Abstract Background Although many conventional healthcare services to prevent postpartum depression are provided face-to-face, physical and psychosocial barriers remain. These barriers may be overcome by using mobile health services (mHealth). To examine the effectiveness of mHealth professional consultation services in preventing postpartum depressive symptoms in real-world settings, we conducted this randomized controlled trial in Japan, where universal free face-to-face perinatal care is available. Methods This study included 734 pregnant women living in Yokohama city who could communicate in Japanese, recruited at public offices and childcare support facilities. The participants were randomized to the mHealth group (intervention, n = 365), where they could use a free app-based mHealth consultation service with gynecologists/obstetricians, pediatricians, and midwives whenever and as many times as they wanted between 6 p.m. and 10 p.m. on weekdays throughout their pregnancy and postpartum periods (funded by the City of Yokohama government) or the usual care group (control, n = 369). The primary outcome was the risk of elevated postpartum depressive symptoms, defined as Edinburgh Postnatal Depression Scale score ≥ 9. Secondary outcomes were self-efficacy, loneliness, perceived barriers to healthcare access, number of clinic visits, and ambulance usage. All outcomes were collected three months post-delivery. We also conducted subgroup analyses assessing the differences in the treatment effect by sociodemographic status. Results Most women completed all questionnaires (n = 639 of 734, response rate: 87%). The mean baseline age was 32.9 ± 4.2 years, and 62% were primipara. Three months post-delivery, women in the mHealth group had a lower risk of elevated postpartum depressive symptoms (47/310 [15.2%]) compared to the usual care group (75/329 [22.8%], risk ratio: 0.67 [95% confidence interval: 0.48–0.93]). Compared with the usual care group, women in the mHealth group had higher self-efficacy, less loneliness, and fewer perceived barriers to healthcare access. No differences were observed in the frequency of clinic visits or ambulance usage. Furthermore, in the subgroup analyses, we did not find differences in the treatment effect by sociodemographic status. Conclusions Local government-funded mHealth consultation services have a preventive effect on postpartum depressive symptoms, removing physical and psychological barriers to healthcare access in real-world settings.

  背景：所得が少ないなどの経済的な困窮は健康に悪影響を及ぼす．経済的に困窮する人々の健康支援は重要な公衆衛生課題であるが，日本では所得が少ないほど必要な医療受診を控えやすいことがかねてより報告されている．経済的に困窮した患者の医療受診を支援する制度のひとつに無料低額診療事業（以下，無低診）がある．2020年度には延べ270万人の無低診の利用者がいるが，日本全体の利用者の実態と制度の課題が共有され議論される場所は乏しい． 方法：日本全国の無低診の実施医療機関から収集された無低診レジストリ研究の登録データと医療ソーシャルワーカーの実践を報告する無低診フォーラムをオンライン開催し，報告内容から無低診の可能性や課題を支援者間で共有した． 結果：無低診フォーラムにはのべ249名，常時200名以上が参加した．無低診レジストリ研究の登録データからは，利用者の約 4 割に過去 1 年間の経済的な理由による受診控えの経験があり，無低診の認知度によっても受診控えが緩和されないこと，利用者のうちの約半数は，今までに生活の困難を誰にも相談しておらず，無低診の利用をきっかけに始まる社会福祉による支援があることが示唆された．医療ソーシャルワーカーの報告からは，無低診による支援戦略をより効果的にする方法や，無低診の利用者における医療への障壁の低減が示唆される一方，無低診施設間の連携の困難さや，診療科や医療機関の規模による無低診の限界，無低診でカバーされない調剤費や訪問看護，介護サービスなどの利用控えの課題が共有された．さらに，無保険の外国人に対して無低診が活用されている現実があるが，病院経営等のさまざまな課題があることなどの問題意識が共有された． 考察：本フォーラムでは，無低診に関連する研究が果たすべき役割も示唆された．まず，レジストリ研究は，今後も多くの日本各地の医療機関と協力し利用者の状況把握をさらに進め，困窮する人々が無低診を利用するための障壁の除去に貢献できる資料を作成していくことが求められる．第二に，無低診により減免した医療費と税制上のインセンティブを考慮した無低診の経営影響を記述することが求められる．最後に，無低診の現代的な社会保障制度の中での役割や位置付けに関するさらなる議論が重要である．

  OBJECTIVE: We aimed to identify the proportion of each medical condition or disease contributing to dizziness and their disposition in the Emergency Department (ED). METHODS: This retrospective, descriptive study examined data from the Osaka Emergency Information Research Intelligent Operation Network system in Japan for the period from January 1, 2018 to December 31, 2020. The inclusion criteria were patients with presumptive ICD-10 codes including "dizziness" or "vertigo". Patient demographics were compared using the χ2 test and Kruskal-Wallis test. Logistic regression analysis was performed to calculate disposition from ED (emergency admission or discharge) over the 3-year study period. The adjusted odds ratio (OR) and 95% confidence interval (CI) were calculated using multivariate analyses. RESULTS: During the 3-year study period, a total of 1,346,457 patients (462,773 in 2018, 468,697 in 2019, and 414,987 in 2020; P <  0.001), including 53,190 patients with dizziness (18,396 in 2018, 18,649 in 2019, and 16,145 in 2020; P = 0.058), were identified as having been transported to hospitals by ambulance in Osaka Prefecture. Dizziness and giddiness (R42) was the most common form of dizziness, in 27,075 cases (9,570 in 2018, 9,613 in 2019, and 7,892 in 2020; P <  0.001; Gender composition showed 10,483 males and 16,592 females.) Vestibular Neuronitis (H81.2) showed significant increase in 2020 compared to the two preceding years (91 in 2018, 119 in 2019, and 130 in 2020, P = 0.003; including 174 males and 167 females, respectively). Of the 53,190 patients with dizziness, 11,862 (22.3% ; 4,323 males, 7,539 females) were admitted to hospital. The odds ratio (OR) for emergency admission for dizziness in 2020 during the COVID-19 pandemic was 0.98 (95% confidence interval (CI), 0.93- 1.03) with reference to 2018. CONCLUSION: Patients with dizziness accounted approximately 4% of ED transportations, with about 20% requiring hospital admission, irrespective of the COVID-19 pandemic. Vestibular neuronitis was significantly increased in 2020.

• Effect of the COVID-19 outbreak on emergency transport of children by an emergency medical service system: a population-based, ORION registry study

  Koshi Ota, Daisuke Nishioka, Yusuke Katayama, Tetsuhisa Kitamura, Jun Masui, Kanna Ota, Masahiko Nitta, Tetsuya Matsuoka, Akira Takasu

  Abstract Background Coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus 2, has spread rapidly around the world. Objective To assess the effect of the COVID-19 pandemic on the emergency medical service (EMS) and hospital admission course for children transported by ambulance. Methods This study was a retrospective, descriptive study with a study period from January 1, 2018 to December 31, 2020 using the Osaka Emergency Information Research Intelligent Operation Network (ORION) system. All children who were transported by ambulance in Osaka Prefecture were included. The main outcome of this study was the rate of difficult-to-transfer cases, which was calculated by univariate and multivariate Poisson regression analyses. Results Over the 3 years between January 1, 2018 and December 31 2020, 1,436,212 patients were transported to hospitals by ambulances in Osaka Prefecture, with children accounting for 102,473 (37,064, 39,590, and 25,819, in 2018, 2019, and 2020, respectively). Poisson regression analysis showed that children were negatively associated with difficult-to-transfer cases (risk ratio (RR) 0.35, 95% CI 0.33 to 0.37). With reference to 2018, 2020 was not significantly associated with difficult-to-transfer cases in children (RR 1.14, 95% CI 0.99 to 1.32, P = 0.075), but was significantly related (RR 1.24, 95% CI 1.21 to 1.27, P < 0.001) to difficult-to-transfer cases in the general population. Conclusion Children were consistently associated with a reduced RR for difficult-to-transfer cases, even in the COVID-19 pandemic in 2020.

• Changes in health-related quality of life scores among low-income patients on social welfare programs in Japan during the COVID-19 pandemic: a single-center repeated cross-sectional study

  Satoshi Wakata, Daisuke Nishioka, Yukio Takaki

  Abstract Background Low-income is one of the well-established determinants of people’s health and health-related behavior, including susceptibility to the coronavirus disease 2019 (COVID-19) infection. Two social welfare services are available in Japan to support financial and medical care among low-income patients: Public Assistance (PA), which provide both minimum income and medical costs; and Free/Low-Cost Medical Care (FLCMC), wherein only medical costs were covered. In this study, changes in Health-Related Quality of Life (HRQOL) scores of low-income patients on PA and FLCMC, before and after COVID-19 pandemic, were described and compared against those that are not utilizing the said services (comparison group) to evaluate the contribution of social welfare services in protecting the HRQOL of the beneficiaries during the pandemic. Methods We used repeated cross-sectional data of adult beneficiaries of FLCMC and PA, as well as those without social welfare services, who regularly visit the Kamigyo clinic in Kyoto, Japan. We collected the data from 2018 and 2021 using a questionnaire on patients’ socioeconomic attributes and the Japanese version of Medical Outcomes Study 12-Item Short Form Health Survey (SF-12). The Japanese version of SF-12 can calculate the three components scores: physical health component summary (PCS), the mental health component summary (MCS), and the role-social component summary (RCS), which can be transformed to a 0–100 range scale with a mean of 50 and standard deviation of 10. Results Data of 200 and 174 beneficiaries in 2018 and 2021, respectively, were analyzed. Low-income patients on social welfare services had lower PCS, and RCS than the comparison group in both years. Multiple linear regression analyses with cluster-adjusted standard error estimator showed that the decline in MCS was significantly higher among FLCMC beneficiaries than in those without welfare services (Beta: -4.71, 95% Confidence Interval [CI]: –5.79 to -3.63, p < 0.01), and a decline in MCS among PA recipients was also observed (Beta: -4.27, 95% CI: -6.67 to -1.87 p = 0.02). Conclusions Low-income beneficiaries of social welfare may have experienced mental health deterioration during the COVID-19 pandemic. To maintain healthy lives during the pandemic, additional support on mental health for low-income recipients of social welfare services may be required.

  OBJECTIVE: This study aimed to compare the short-term outcomes between laparoscopic and open distal pancreatectomy for lesions of the distal pancreas from a real-world database. SUMMARY BACKGROUND DATA: Reports on the benefits of laparoscopic distal pancreatectomy include two randomized controlled trials; however, large-scale, real-world data are scarce. METHODS: We analyzed the data of patients undergoing laparoscopic or open distal pancreatectomy for benign or malignant pancreatic tumors from April 2008 to May 2020 from a Japanese nationwide inpatient database. We performed propensity score analyses to compare the in-hospital mortality, morbidity, readmission rate, reoperation rate, length of postoperative stay, and medical cost between the two groups. RESULTS: From 5,502 eligible patients, we created a pseudo-population of patients undergoing laparoscopic and open distal pancreatectomy using inverse probability of treatment weighting. Laparoscopic distal pancreatectomy was associated with lower in-hospital mortality during the period of admission (0.0% vs. 0.7%, P<0.001) and within 30 days (0.0% vs. 0.2%, P=0.001), incidence of reoperation during the period of admission (0.7% vs. 1.7%, P=0.018), post-pancreatectomy hemorrhage (0.4% vs. 2.0%, P<0.001), ileus (1.1% vs. 2.8%, P=0.007), and shorter postoperative length of stay (17 vs. 20 d, P<0.001). CONCLUSIONS: The propensity score analysis revealed that laparoscopic distal pancreatectomy was associated with better outcomes than open surgery in terms of in-hospital mortality, reoperation rate, postoperative length of stay, and incidence of postoperative complications such as post pancreatectomy hemorrhage and ileus.

• Changes in Health-related Quality of Life Among Impoverished Persons in the Free/Low-Cost Medical Care Program in Japan: Evidence From a Prospective Cohort Study.

  Daisuke Nishioka, Chisato Tamaki, Noriko Furuita, Hirokazu Nakagawa, Erin Sasaki, Rika Uematsu, Takeshi Ozaki, Satoshi Wakata, Naoki Kondo

  BACKGROUND: The Free/Low-Cost Medical Care Program (FLCMC) can subsidize the payment (exempt/lower) in designated institutions in Japan. Given that poverty is a multidimensional concept including social isolation, the FLCMC applicants may need social support over and above financial aid to improve their quality of life. However, there was no data to discuss what services should be provided and to whom. Hence, we aimed to describe the changes in health-related quality of life scores among users of the FLCMC, with respect to their socioeconomic backgrounds. METHODS: This cohort study included patients who newly used FLCMC from July 2018 to April 2019. We used patients' social work records, obtained at baseline, and self-report questionnaires on the Medical Outcomes Study 8 Items Short Form Health Survey (SF-8), measured both at baseline and six-month-after the application. We used the change in physical and mental health component summary score (PCS-8 and MCS-8) as outcome variables. RESULTS: Multiple linear regression analyses, adjusting for age, sex, healthcare institute, and baseline PCS-8 and MCS-8, showed that lower income was associated with an increase in PCS-8 (coef. -0.09; 95% CI, -0.15 to, -0.03) and MCS-8 (coef. -0.04; 95% CI, -0.11, to 0.03). Living alone (versus. living with someone) was potentially associated with a decrease in both PCS-8 (coef. -1.58; 95% CI, -7.26 to 4.09) and MCS-8 (coef. -3.62; 95% CI, -9.19 to 1.95). CONCLUSIONS: Among patients using FLCMC, those who live alone may need additional support. Further study testing the generalizability of the findings is required.

  This study aimed to elucidate the pathomechanism of peripheral neuropathy (PN) in microscopic polyangiitis (MPA) and to identify biomarkers useful for diagnosis and severity assessment. Patients with MPA (n = 37) and other non-inflammatory neurological diseases (ONDs; n = 12) were enrolled, and the peripheral nerves of all patients were evaluated using nerve conduction studies. We compared the clinical characteristics and 14 serum biomarker profiles among patients with MPA and PN, MPA without PN, and ONDs. Patients with MPA had a higher prevalence of motor neuropathy than patients with ONDs. Among the patients with MPA, those with motor neuropathy had significantly higher total Birmingham Vasculitis Activity Scores and serum levels of C-reactive protein (CRP), tissue inhibitor of metalloproteinase-1 (TIMP-1), and interleukin-6 than patients without motor neuropathy. Multivariable analyses adjusted for age, serum CRP level, and diabetes mellitus showed that high serum levels of TIMP-1 were independently related to a diagnosis of motor neuropathy in MPA. Additionally, there were significant negative correlations between the serum levels of TIMP-1 and compound muscle action potential amplitudes. Serum levels of TIMP-1 may be associated with the pathomechanism of motor neuropathy in MPA and could be a useful biomarker for diagnosing and evaluating the severity of motor neuropathy in MPA.

  The aim of this multi-center retrospective study was to clarify the prognostic factors for respiratory-related death in patients with rheumatoid arthritis (RA) complicated interstitial lung disease (ILD). Patient background data, treatment regimen, and disease activity indicators of RA and ILD at baseline, 6 months after diagnosis of ILD, and at the last follow-up visit were extracted. A total of 312 patients with RA-ILD (17 patients who died from respiratory-related causes and 295 survivors) were included. Patients who died from respiratory-related causes had an older median age, higher proportion of males, and a higher anti-cyclic citrullinated peptide antibody positivity rate than survivors (P = 0.0001, 0.038, and 0.016, respectively); they also had significantly higher baseline serum levels of KL-6 than survivors (P = 0.013). Patients who died from respiratory-related causes showed significantly greater changes in serum KL-6 levels between the six-month timepoint and the last visit (ΔKL-6 [6 m-last]) than survivors (P = 0.011). Multivariate analysis showed that the ΔKL-6 (6 m-last) corrected by disease duration was a predictor of respiratory disease-related death in patients with RA-ILD (P <0.0001). Long-term increase in serum KL-6 levels is associated with respiratory disease-related death in patients with RA-ILD.

• A glucocorticoid-receptor agonist ameliorates bleomycin-induced alveolar simplification in newborn rats

  Shoichi Ishikawa, Tohru Ogihara, Shigeo Yamaoka, Jun Shinohara, Shigeru Kawabata, Yoshinobu Hirose, Daisuke Nishioka, Akira Ashida

  BACKGROUND: Glucocorticoids (GCs) are highly effective yet problematic agents against bronchopulmonary dysplasia (BPD). The dimeric trans-activation of GCs induces unfavorable effects, while monomeric trans-repression suppresses inflammation-related genes. Recently, non-steroidal-selective glucocorticoid-receptor agonists and modulators (SEGRAMs) with only the trans-repressive action have been designed. METHODS: Using a bleomycin (Bleo)-induced alveolar simplification newborn rat model (recapitulating arrested alveolarization during BPD), we evaluated the therapeutic effects of compound-A (CpdA), a SEGRAM. Sprague-Dawley rats were administered Bleo from postnatal day (PD) 0 to 10 and treated with dexamethasone (Dex) or CpdA from PD 0 to 13. The morphological changes and mRNA expression of inflammatory mediators, including interleukin (IL)-1β, C-X-C motif chemokine ligand 1 (CXCL1), and C-C motif chemokine 2 (CCL2) were investigated. RESULTS: Similar to the effects of Dex, CpdA exerted protective effects on morphological derangements and inhibited macrophage infiltration and production of pro-inflammatory mediators in Bleo-treated animals. The effects of CpdA were probably mediated by GC receptor (GR)-dependent trans-repression, because unlike the Dex-treated group, anti-inflammatory genes specifically induced by GR-dependent trans-activation (such as "glucocorticoid-induced leucine zipper, GILZ") were not upregulated. CONCLUSIONS: CpdA improved lung inflammation, inhibited the arrest of alveolar maturation, and restored histological and biochemical changes in a Bleo-induced alveolar simplification model. IMPACT: SEGRAMs have attracted widespread attention because they are expected to not exhibit unfavorable effects of GCs. Compound A, one of the SEGRAMs, improved lung morphometric changes and decreased lung inflammation in a bleomycin-induced arrested alveolarization, a newborn rat model representing one of the main features of BPD pathology. Compound A did not elicit bleomycin-induced poor weight gain, in contrast to dexamethasone treatment. SEGRAMs, including compound A, may be promising candidates for the therapy of BPD with less adverse effects compared with GCs.

• [Childhood experiences of seeking parental support, social interactions, and interpersonal relationships in adulthood: a cross-sectional study].

  Yuri Nakamura, Maho Haseda, Daisuke Nishioka, Airi Amemiya, Keiko Ueno, Naoki Kondo

  Objectives Some young adults often tend to perceive interpersonal relationships and social interactions as stressful, and as such, avoid them. Seeking help from parents and interactions with neighbors during childhood are known to be important in forming positive impressions of people, thereby influencing help-seeking behavior in adulthood. However, it remains unclear how these experiences are related and how they influence interpersonal relationships in adulthood. This study aimed to investigate whether childhood experience(s) of social interactions in the community has any modifying effect on the association between seeking support from parents in childhood and avoidance of interpersonal relationships in adulthood.Methods Data pertaining to 1,274 individuals (aged 18 to 39 years) were collected from a questionnaire survey conducted in 2018 by Nagoya City of Japan. Modified Poisson regression analyses were performed to estimate the prevalence ratio of current avoidance of interpersonal relationships depending on the experience(s) of seeking help from a parent (father/mother analyzed respectively) and participating in community events in childhood. Data were stratified according to gender, and adjusted for age, parents' educational background, mother's working status in childhood, subjective recognition of economic status in childhood and seeking help from the other parent. Effect estimates were calculated to evaluate the existence of any modifying effect.Results No modifying effect of participating in community events in childhood was seen in the association between experience of seeking help from the father and current avoidance of interpersonal relationships, in either gender. Regarding experience of seeking help from the mother, a modifying effect was seen in men. Among men who had sought help from their mother, those who had participated in community events were less likely to avoid interpersonal relationships in adulthood.Conclusion In order to reduce the tendency to avoid interpersonal relationships in adulthood, childhood experiences of seeking help from the mother and participating in community events may be important, particularly for men. In addition to appropriate parental support, promoting interactive events for children in communities may mitigate the problem of poor social skills later in life.

• Suicidal ideation and suicide attempts among older recipients of public welfare assistance in Japan

  Shiho Kino, Andrew Stickley, Daisuke Nishioka, Keiko Ueno, Masashige Saito, Toshiyuki Ojima, Naoki Kondo

  BACKGROUND: The high suicide rate among older adults is an important public health issue. Financial insecurity has been linked to suicidal behaviour. Despite this, as yet, there has been little research on suicide-related behaviours among older recipients of public welfare. This study will examine if suicidal ideation and suicide attempts are more prevalent in older recipients of public welfare assistance in Japan. METHODS: This cross-sectional study analysed data from 16 135 adults aged ≥65 years who participated in the 2019 wave of the Japan Gerontological Evaluation Study. Information was obtained on receiving public welfare assistance, lifetime suicidal ideation and attempts, and a variety of covariates. Poisson regression analysis with robust variance estimates was used to examine associations. RESULTS: Suicidal ideation was reported by 4.8% of the participants, while the corresponding figure for attempted suicide was 2.2%. In fully adjusted analyses public welfare recipients had an almost 1.5 times higher prevalence of lifetime suicidal ideation (prevalence ratio, PR 1.47, 95% CI 1.02 to 2.13), and an almost two times higher prevalence of attempted suicide (PR 1.91, 95% CI 1.20 to 3.04) when compared with their counterparts not receiving public welfare assistance. CONCLUSION: Older recipients of public welfare have a higher prevalence of suicidal behaviour in Japan. An urgent focus is now warranted on this vulnerable population to determine the specific factors underlying this association.

• Risk profiles of frequent outpatients among public assistance recipients in Japan: a retrospective cohort study using a classification and regression trees algorithm

  Daisuke Nishioka, Shiho Kino, Keiko Ueno, Naoki Kondo

  OBJECTIVES: Although several individual risk factors of frequent outpatient attendance (FOA) have previously been reported, identifying a specific risk profile is needed to provide effective intervention for impoverished citizens with complex biopsychosocial needs. We aimed to identify potential risk profiles of FOA among public assistance recipients in Japan by using classification and regression trees (CART) and discussed the possibilities of applying the CART to policypractice as compared with the results of conventional regression analyses. DESIGN: We conducted a retrospective cohort study. SETTING: We used secondary data from the public assistance databases of six municipalities in Japan. PARTICIPANTS: The study population included all adults on public assistance in April 2016, observed until March 2017. We obtained the data of 15 739 people on public assistance. During the observational period, 435 recipients (2.7%) experienced FOA. OUTCOME MEASURE: We dichotomised a cumulative incidence of FOA during the study period into a binary variable of exhibiting FOA or not. We adopted the definition of FOA by the Ministry of Health, Labour, and Welfare: visiting the same medical institution more than 15 days a month. RESULTS: The results of the CART showed that an employed subpopulation with mental disabilities exhibited the highest risk of FOA (incidence proportion: 16.7%). Meanwhile, multiple Poisson regression showed that the adjusted incidence ratio of being unemployed (vs employed) was 1.71 (95% CI 1.13 to 2.59). CONCLUSIONS: Using the CART model, we could identify specific risk profiles that could have been overlooked when considering only the risk factors obtained from regression analysis. Public health activities can be provided effectively by focusing on risk factors and the risk profiles.

  BACKGROUND: The coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus 2, has spread rapidly across the world. OBJECTIVE: To assess the influence of the COVID-19 pandemic on the emergency medical service (EMS) for transportation of pregnant women by ambulance. METHODS: This study was a retrospective, descriptive study using the Osaka Emergency Information Research Intelligent Operation Network system, and included pregnant women transported by ambulance in Osaka Prefecture between January 1, 2018 and December 31, 2020. The main outcome of the study was difficulty in obtaining hospital acceptance for transfer of patients (difficult-to-transfer cases). We calculated the rates of difficult-to-transfer cases using univariate and multivariate analyses. RESULTS: Of the 1 346 457 total patients transported to hospitals by ambulance in Osaka Prefecture during the study period, pregnant women accounted for 2586 (909, 943, and 734, in 2018, 2019, and 2020, respectively). Logistic regression analysis revealed that pregnant women were negatively associated with difficult-to-transfer cases (adjusted OR 0.36, 95% CI 0.26-0.50). Compared with 2018, 2020 was significantly associated with difficult-to-transfer cases (adjusted OR 1.27, 95% CI 1.24-1.30). CONCLUSION: Pregnant women were consistently associated with reduced odds for being difficult-to-transfer cases. The COVID-19 pandemic might have influenced difficult-to-transfer cases in 2020.

• Public assistance program and depressive symptoms of the recipient: a cross-sectional Japan Gerontological Evaluation Study.

  Shiho Kino, Daisuke Nishioka, Keiko Ueno, Maho Haseda, Naoki Kondo

  Abstract Background Mental health conditions among older recipients of public assistance should be considered because it has been reported that public assistance recipients tend to have higher risks of morbidity than non-recipients, and mental health is strongly related to frailty. We aimed to examine whether older recipients of public assistance were more likely to have depressive symptoms compared to non-recipients. Methods Data were obtained from the Japan Gerontological Evaluation Study, a 2016 community-based study of older adults. Poisson regression analyses with a robust error variance using fixed effects were conducted to examine the relationship between receiving public assistance and depressive symptoms controlling for sociodemographic factors. Depressive symptoms were assessed by the Geriatric Depression Scale 15. Results We found that the older recipients of public assistance were 1.57 times (95% confidence interval [CI]: 1.47, 1.67) more likely to have depressive symptoms compared to non-recipients. We also found that, when additionally adjusting for indicators of social participation, this relationship was slightly attenuated; however, the recipients still had worse mental health issues (Prevalence ratio: 1.33; 95% CI: 1.25, 1.42). Conclusions Even after controlling for sociodemographic factors, older recipients of public assistance tended to be more depressed than non-recipients. However, our findings also indicated that social participation could slightly attenuate the negative relationship between receiving public assistance and depressive symptoms. Therefore, the public assistance program needs to consider the inclusion of mental healthcare support in addition to financial support.

• [Expectations and problems of the healthcare management support program for public assistance recipients].

  Keiko Ueno, Daisuke Nishioka, Naoki Kondo

  Objectives In recent years, the importance of healthcare support for public assistance recipients has been recognized, and healthcare support measures have been implemented for them. This study aimed to investigate the expectations and problems of welfare offices, as well as their requests to the central government and prefectures about the healthcare management support program for public assistance recipients, which has been mandated since 2021.Methods In November 2019, snowball sampling was used to select 23 welfare offices for sending self-administered questionnaires about the healthcare management support program. Respondents were asked open-ended questions about their expectations and problems regarding the program, as well as their requests to the central government and prefectures. A subsequent interview survey was conducted from November 2019 to February 2020, gathering additional information on the questionnaire survey.Results We received consent for the questionnaire survey and interview survey from 16 welfare offices (response rate 69.6%). It was revealed that the staff in charge of the healthcare management support program at the welfare office expected the program to improve recipients' health awareness and condition and for it to be applied to other residents in the community. They reported difficulty in developing the implementation system, setting up the indicators and target population, and retaining health professionals. They requested the central government and prefectures to clarify the indicators and the criteria for evaluation, provide reference materials, introduce precedents, communicate and coordinate with welfare offices and related organizations in the community, hold meetings to share information, and secure financial resources.Conclusion Findings from our study suggest a need to strengthen the cooperation between the central government, prefectures, and local governments and to establish a multilayered system to implement the healthcare management support program effectively in welfare offices.

• Changes in social relationships by the initiation and termination of public assistance in the older Japanese population: A JAGES panel study.

  Shiho Kino, Daisuke Nishioka, Keiko Ueno, Masashige Saito, Naoki Kondo

  Public assistance recipients in Japan are financially empowered by social welfare but are also exposed to social stigma. Therefore, when their status of receiving public assistance changes, the conditions of their social life likely change. We examined whether the social relationships of older adults receiving public welfare are influenced by either starting or terminating their use of public assistance. This study used the Japan Gerontological Evaluation Study panel data from 2013 to 2016. To measure social relationships, we used four indicators: the frequency of meeting with friends, the number of friends whom the participants had met with in the past month, their frequency of participating in sports clubs, and their frequency of participating in hobby clubs. In the analyses, changes in social relationships between 2013 and 2016 were used as the study outcomes. Linear regression analyses were conducted to examine if their social relationships changed before and after starting or terminating public assistance while adjusting for confounders. We found that people who stopped receiving public assistance experienced an increase in their frequency of meeting with friends (coefficient: 0.56; 95% CI: 0.06, 1.07), the number of friends (coefficient: 0.60; 95% CI: 0.20, 0.99), participation in sports clubs (coefficient: 0.91; 95% CI: 0.46, 1.39), and participation in hobby clubs (coefficient: 0.70; 95% CI: 0.26, 1.13) compared to those who continued to receive public assistance. Contrarily, the measured social relationships did not change after the participants started receiving public assistance. Our main findings were that terminating one's reception of public assistance increases informal socializing and social participation while starting public assistance does not interrupt pre-existing relationships. These findings contribute to the literature by adding that social relationships are not negatively influenced by either terminating or starting public assistance. Targeted promotions of social connections would effectively maintain the health statuses of low-income older adults.

• Role of psychosocial factors in starting and leaving public assistance programs by older Japanese population: Longitudinal Japan Gerontological Evaluation Study

  Shiho Kino, Daisuke Nishioka, Keiko Ueno, Naoki Kondo

  BACKGROUND: Public assistance programs guarantee a minimum living standard, promoting independence for impoverished citizens. Although public assistance eligibility is mainly based on economic factors like poverty, psychosocial factors may be important in initiating and terminating participation. We explored factors governing commencement and termination of public assistance by the older Japanese population between 2013 and 2016. METHODS: We used panel data from the Japan Gerontological Evaluation Study (JAGES), conducted in 2013 and 2016. Fixed-effects regression was used to examine variables in 2013 that were related to receiving public assistance in 2016. The Tokyo Metropolitan Institute of Gerontology -competence index (TMIG-CI) was used to assess higher-level activities of daily living (ADL, i.e., instrumental ADL, intellectual activity, and social role). The role of individual perceptions of community social cohesion (community trust, mutual help, and attachment), and sociodemographic factors were considered. RESULTS: While 215 people (0.5%) started receiving public assistance between 2013 and 2016, almost 50% stopped participating. People with higher perceived mutual community help were 1.21 times (95% confidence interval [CI]: 1.02-1.46) more likely to commence public assistance three years later. Public assistance recipients who felt community attachment to their resident community, and had social roles were 1.16 (95% CI: 1.06-1.28) and 1.15 (95% CI: 1.01-1.30) times more likely to give up public assistance three years later, respectively, independent of socioeconomic statuses. CONCLUSION: Psychosocial factors, including maintaining good relationships with community residents, could be important in accessing and terminating public assistance services.

• Neuron-specific enolase level is a useful biomarker for distinguishing amyotrophic lateral sclerosis from cervical spondylotic myelopathy.

  Akihiro Tsukahara, Takafumi Hosokawa, Daisuke Nishioka, Takuya Kotani, Shimon Ishida, Tohru Takeuchi, Fumiharu Kimura, Shigeki Arawaka

  AbstractThe current study aimed to evaluate whether cerebrospinal fluid (CSF) neuron-specific enolase (NSE) levels are elevated in amyotrophic lateral sclerosis (ALS) and are effective in distinguishing ALS from cervical spondylotic myelopathy (CSM). We retrospectively evaluated 45 patients with ALS, 23 with CSM, 28 controls, and 10 with Parkinson’s disease (PD) who underwent analysis of CSF NSE levels. The control group comprised patients aged above 45 years who underwent lumbar puncture because of suspected neurological disorders that were ruled out after extensive investigations. CSF NSE levels were evaluated using the electro-chemiluminescent immunoassay. The ALS group had significantly higher CSF NSE levels than the CSM and control groups (P < 0.001 for both comparisons). The CSM, control, and PD groups did not significantly differ in terms of CSF NSE levels. A receiver-operating characteristic curve analysis was performed to assess the diagnostic value of CSF NSE levels in distinguishing ALS from CSM. The area under the curve for CSF NSE levels was 0.86. The optimal cutoff value was 17.7 ng/mL, with a specificity of 87% and a sensitivity of 80%. Hence, CSF NSE levels are elevated in ALS and are effective in distinguishing ALS from CSM.

• Medical expenditure after marginal cut of cash benefit among public assistance recipients in Japan: natural experimental evidence.

  Daisuke Nishioka, Reo Takaku, Naoki Kondo

  BACKGROUNDS: Income reduction in poor households affects healthcare demands for impoverished population. However, the impact of reduced benefits for public assistance recipients, who can use medical services for free, on healthcare costs has not been examined. We hypothesised that marginal cuts in benefits increase recipients' medical expenditure by extra demand for medical care. We tested this hypothesis using public assistance databases of Japan. METHODS: The study population comprised households in five municipalities receiving public assistance between April 2016 and September 2018. The households have a child aged 12-60 months and receive a monthly child-support income of US$150, which reduces by US$50 when the child turns 36 months of age. Our analysis comprised an age-based sharp regression-discontinuity study. RESULTS: We observed 4893 household-months (11 032 person-months). When a firstborn child reached 36 months, their frequency of outpatient visits and healthcare costs by recipients, except for the firstborn child, increased (0.45, 95% CI: 0.30 to 0.61; US$111.2, 95% CI: 20.7 to 201.7), while those of the firstborn child did not increase significantly. The monthly medical expenditure per household increased by US$248.6 (95% CI: 25.4 to 471.7). Inpatient medical costs increased significantly (US$64.3, 95% CI: 8.4 to 120.2). CONCLUSIONS: Government savings through income reduction were offset by increased medical expenditure. This may be due to recipients' behavioural change and their worsening health conditions. To prevent excessive medical expenditure, policymakers should consider how income reduction affects the behaviour and health of the impoverished population.

• Regression discontinuity of blood culture contamination rate after changing of disinfectants: retrospective observational study.

  Koshi Ota, Daisuke Nishioka, Yuri Ito, Emi Hamada, Naomi Mori, Tomonobu Nishii, Kanna Ota, Yuriko Shibata, Akira Takasu

  AbstractBlood cultures are indispensable for detecting life-threatening bacteremia. Little is known about associations between contamination rates and topical disinfectants for blood collection in adults. We sought to determine whether a change in topical disinfectants was associated with the rates of contaminated blood cultures in the emergency department of a single institution. This single-center, retrospective observational study of consecutive patients aged 20 years or older was conducted in the emergency department (ED) of a university hospital in Japan between August 1, 2018 and September 30, 2020. Pairs of blood samples were collected for aerobic and anaerobic culture from the patients in the ED. Physicians selected topical disinfectants according to their personal preference before September 1, 2019; alcohol/chlorhexidine gluconate (ACHX) was mandatory thereafter, unless the patient was allergic to alcohol. Regression discontinuity analysis was used to detect the effect of the mandatory usage of ACHX on rates of contaminated blood cultures. We collected 2141 blood culture samples from 1097 patients and found 164 (7.7%) potentially contaminated blood cultures. Among these, 445 (20.8%) were true bacteremia and 1532 (71.6%) were true negatives. Puncture site disinfection was performed with ACHX for 1345 (62.8%) cases and with povidone-iodine (PVI) for 767 (35.8%) cases. The regression discontinuity analysis showed that mandatory ACHX usage was significantly associated with lower rates of contaminated blood cultures by 9.6% (95% confidence interval (CI): 5.0%–14.2%, P < 0.001). Rates of contaminated blood cultures were significantly lower when ACHX was used as the topical disinfectant.

  Serum cytokine levels were comprehensively measured, and the association with cerebrovascular lesions on brain magnetic resonance imaging (MRI) in microscopic polyangiitis (MPA) patients was investigated. The initial serum granulocyte-macrophage colony-stimulating factor (GM-CSF) levels were significantly higher in the high-grade white matter hyperintensities (WMH) group than those in the low-grade WMH group. In multivariate analyses, high serum levels of GM-CSF were independently associated with high-grade WMH. The initial serum GM-CSF levels correlated positively with the Birmingham Vasculitis Activity Score and semi-quantitative scales of WMH. The initial serum GM-CSF levels were associated with the severity of WMH in MPA patients.

• Determinants of reach counts on medical social media: Evidence from a facebook community page metrics.

  Daisuke Nishioka, Toru Tsuboya

  Sharing medical information using social media became popular. We aimed to identify what sort of posts can increase reach counts. We used metrics data of 40 posts on the Japan Primary Care Association Commission on Social Determinants of Health (JPCA-CSDH) Facebook community page. The most popular post was the one about the position paper on health inequality (Mie-statement). The video posts significantly earned 175% more reach counts (vs posts only with letters). Each one percent word counts increase was associated with a 31% increase in reach counts. Videos and more words may deliver medical information effectively.

• Sociodemographic inequities in dental care utilisation among governmental welfare recipients in Japan: a retrospective cohort study.

  Daisuke Nishioka, Keiko Ueno, Shiho Kino, Jun Aida, Naoki Kondo

  Abstract Background Maintaining oral health is one of the global public health challenges. Income and out-of-pocket payments for dental care services are predictors of dental care utilisation. Although public assistance programmes guarantee income security for impoverished people, access barriers other than financial costs may cause unmet dental care needs. We aimed to explore the potential sociodemographic factors determining dental care utilisation among recipients of public assistance in Japan using linkage data of public assistance database and medical assistance claim data administered by municipalities. Methods This was a retrospective cohort study involving a sample of public assistance recipients. We extracted the recipients’ sociodemographic data (age, sex, household number, employment status, nationality, disability certificates, and long-term care status) in January 2016 and observed them until December 2016 to identify incidences of dental care utilisation as outcomes. We performed a multivariable modified Poisson regression analysis with a robust standard error estimator to calculate the incidence ratio (IR) of dental care utilisation in each variable. Results We identified a total of 4497 recipients at risk. Among them, 839 recipients used dental care services. Younger age was associated with a higher incidence of dental care utilisation. The female recipients had a higher incidence of dental care utilisation when compared to the male ones (adjusted IR, 1.22; 95% confidence interval [CI], 1.08–1.38). Immigrant recipients had a higher incidence of dental care utilisation than the Japanese ones (IR, 1.53; 95% CI, 1.16–2.01). Recipients with mental disabilities had higher incidences than those without disability certificates (IR, 1.30; 95% CI, 1.08–1.56). Conclusions Non-financial sociodemographic inequities in dental care utilisation stemming from age, sex, nationality, and presence of mental disability were found despite minimum income protection and equitable financial dental service access amongst public assistance recipients in Japan. Providing targeted preventive care and treatments for dental care among underserved populations is required to tackle oral health inequities.

• Non-financial social determinants of diabetes among public assistance recipients in Japan: A cohort study.

  Daisuke Nishioka, Junko Saito, Keiko Ueno, Naoki Kondo

  AIMS: Poverty is an important social determinant of diabetes. Poverty is a multidimensional concept including non-financial difficulties such as social isolation and exclusion from communities. Many countries provide financial social assistance programs for those in need. This study aimed to explore non-financial social determinants of diabetes among public assistance recipients in Japan, by using linkage data of two municipal public assistance databases and medical assistance claim data. MATERIALS AND METHODS: We conducted a retrospective cohort study. Public assistance is provided to households below the poverty line to ensure their income security. We extracted recipients' sociodemographic factors of January 2016 (household number and employment status as non-financial social determinants of diabetes) and identified the incidence of diabetes diagnosis until December 2016 as the outcome. RESULTS: We included the data of 2,698 younger individuals (<65 years old) and 3,019 older individuals (>65 years old). A multivariable Poisson regression, with a robust standard error estimator, showed that among 2,144 younger recipients at risk, unemployment and living alone were slightly associated with one-year cumulative incidence of diabetes diagnosis (adjusted incidence ratio [IR]: 1.20, 95% confidence interval [CI]: 0.93-1.54 and IR: 1.15, 95% CI: 0.89-1.48, respectively). Among 2,181 older recipients at risk, there was no strong association between their sociodemographic factors and incidence of diabetes diagnosis CONCLUSIONS: Unemployment and living alone may be additional risk factors for diabetes among younger public assistance recipients. Multidimensional supports assuring financial and non-financial securities are needed to prevent diabetes among people living in poverty.

• Single-parenthood and health conditions among children receiving public assistance in Japan: a cohort study.

  Daisuke Nishioka, Junko Saito, Keiko Ueno, Naoki Kondo

  BACKGROUND: Children's healthy development is important. While governmental public assistance benefits financially troubled families, it cannot compensate for a lack of social support. Single-parenthood is a health risk factor for children owing to low-income-associated food insecurity and stress. No study has investigated the association between single-parenthood and health status in children from families receiving public assistance. This study aimed to examine the association between single-parent households and children's health among public assistance recipients in Japan by using linkage data of two municipal public assistance databases and administrative medical assistance data. METHODS: We performed a retrospective cohort study. Public assistance for households below the poverty line ensures income security and medical care. The study population included all children aged 15 or younger availing public assistance in January 2016. We extracted recipients' sociodemographic factors from January 2016 and identified the incidence of childhood diseases' diagnosis until December 2016 as the outcome, including 1) acute upper respiratory infections; 2) influenza and pneumonia; 3) injuries, including fractures; 4) intestinal infectious diseases; 5) conjunctivitis; 6) asthma; 7) allergic rhinitis; 8) dermatitis and eczema, including atopic dermatitis; and 9) diseases of the oral cavities, salivary glands, and jaws, such as tooth decay or dental caries. RESULTS: Among the 573 children, 383 (66.8%) lived in single-parent households. A multivariable Poisson regression, with a robust standard error estimator, showed that single-parenthood is associated with a higher prevalence of asthma (incidence ratio [IR] = 1.62; 95% confidence interval [CI], 1.16-2.26), allergic rhinitis (IR = 1.41; 95% CI, 1.07-1.86), dermatitis and eczema (IR = 1.81; 95% CI, 1.21-2.70), and dental diseases (IR = 1.79; 95% CI, 1.33-2.42) compared to non-single parent households, whereas little association was found between single-parenthood and children's acute health conditions. CONCLUSIONS: Among public assistance recipients, living in single-parent households may be a risk factor for children's chronic diseases. The Japanese public assistance system should provide additional social care for single-parent households. Further investigations are necessary using more detailed longitudinal data, including environmental factors, the severity of children's health conditions, contents of medical treatments, and broader socioeconomic factors.

• Frequent outpatient attendance among people on the governmental welfare programme in Japan: assessing both patient and supplier characteristics.

  Daisuke Nishioka, Junko Saito, Keiko Ueno, Naoki Kondo

  OBJECTIVES: Using linkage data from two municipal public assistance databases and medical assistance claim data, this study aimed to identify characteristics associated with frequent outpatient attendance by people on public assistance, who can access medical care services without copayment in Japan, with simultaneous consideration of supplier factors. DESIGN: We performed a retrospective cohort study. SETTING: We used secondary data from the public assistance databases of two suburban municipalities in Japan. PARTICIPANTS: The study population included all adults on public assistance in January 2016, who were observed until December 2016. A total of 6016 people was included in the analysis. Among them, 2956 (49.1%) were men, and 2030 (33.7%) were living alone. OUTCOME MEASURE: We adopted the definition of frequent outpatient attendance by the Japanese Ministry of Health, Labour and Welfare, visiting the same medical facility 15 times or more in a month for the same health problem. RESULTS: Of 6016 included people, 139 (2.3%) were engaged in frequent outpatient attendance. Multiple Poisson regression showed that, as for the individual factors, the adjusted incidence ratio for frequent outpatient attendance was 1.58 (95% CI 1.05 to 2.39) for people living alone (vs living with others). As for the suppliers, the adjusted incidence ratio for frequent outpatient attendance was 1.74 (95% CI 1.20 to 2.52) for private institutions (vs medical corporations). There were no significant associations between frequent outpatient attendance and individual disability certificate or long-term care needs. CONCLUSIONS: This study suggests that among recipients of public assistance who can access medical services without copayment, social isolation may be associated with frequent outpatient attendance. Private clinics may also be associated with this phenomenon. Interventions to prevent social isolation-by for example, providing health and social care in a more integrated manner-may thus be efficacious in reducing the healthcare demands of socially vulnerable individuals.

• [Development of livelihood difficulties assessment scales for clinicians].

  Daisuke Nishioka, Keiko Ueno, Mitsuhiko Funakoshi, Masashige Saito, Naoki Kondo

  Objectives Poverty is a well-known major social determinant of health. Poverty has been conceptualized as multidimensional livelihood difficulties that include material deprivation, financial difficulties, and social isolation. Through their clinical practice, some health care institutions have tried to address social risks among patients. However, standardized assessment tools that can detect patients' livelihood difficulties are not well established. The aims of this study were to develop brief screening tools to assess patients' livelihood difficulties, and to examine the validity and reliability of these tools in Japanese health care institutes.Methods We used secondary data from a cross-sectional questionnaire survey. The respondents of the survey were adult patients from five hospitals belonging to Japan Health Promoting Hospitals and Service Networks. The questionnaire included 25 questions that assessed patients' poverty. An iterated principal factor analysis with Promax rotation was performed and scales to assess patients' livelihood difficulties were developed. This was followed by an examination of the scales' validity and internal consistency using standardized Cronbach's alpha. Further, we built brief assessment tools by selecting questions that showed high factor loading.Results A total of 265 participants were included in the study. The response rate was 75.1%. The results of factor analysis suggested that data was affected by patients' financial difficulties and social isolation. Eight questions on the financial difficulty scale and five questions on the social isolation scale showed factor loadings greater than 0.40. The standardized Cronbach's alpha coefficient was 0.88 for the financial difficulty scales and 0.74 for the social isolation scales. Finally, a brief assessment tools that included two questions from each scale was developed.Conclusion This tool may be used as a screening tool for patients' livelihood difficulties in the health records of each clinic/hospital, and may help patients effectively receive integrated medical and social care. In order to use this scale in practice, under a well-established community-based integrated care system, it may be necessary to establish a standardized scoring system and diagnostic threshold to verify the generalizability of the scale at healthcare institutes with different characteristics.

The case was a 9th decade female with dementia, who had anemia pointed out on a routine laboratory check. The type of anemia was macrocytic(MCV>130 fL). The serum Vit.B12 and folate levels were markedly decreased. However, her anemia was not improved despite supplementation with Vit.B12 and folate (data on MCV were improved). The WBC increased gradually, but she subsequently died. Laboratory data were assessed by three doctors (DN, NM, and TT: blood cell counts, smear morpholo- gy of peripheral blood cells, and clinical chemistry, respectively). They diagnosed the patient with a hema- tological disorder, probably neoplastic hematological diseases; however, it was very difficult to make a further clinical diagnosis because of the necessary data not presented at this meeting. The final diagnosis was acute myeloid leukemia (AML-M4). The direct cause of death was rupture of her spleen due to the massive infil- tration of neonlastic cells. rReviewl.

• 歯性感染に起因したStreptococcus mitisによる細菌性肝膿瘍の1例

  西岡大輔, 安達哲史, 武田悟秋, 後藤慶太郎, 柿本年春

  65歳男。3日前から続く発熱と関節痛を主訴に受診した。腹部造影CTで肝S8に50mm大の腫瘤性病変を認め、肝膿瘍・敗血症の疑いで精査加療目的に入院となった。血液検査で炎症反応とビリルビンの高値を認め、Meropenem 1.5g/日の投与を開始した。入院3日目に経皮経肝膿瘍ドレナージ(PTAD)を施行したところ、炎症所見は速やかに改善した。血液培養と膿瘍培養でS.mitisが同定され、入院7日目に血液培養陰性が確認された。同日に抗菌薬をAmpicillin/Sulbactam 9g/日へ変更し、17日目にPTADを抜去した。歯科による診察では口腔内環境が不衛生であり、下顎骨内に進展した齲歯が認められ、中等度の歯周炎と診断された。経食道心臓超音波検査で感染性心内膜炎を疑わせる所見は認めなかった。PTAD抜去後の経過は良好で、入院30日目に退院となった。

  医療機関が社会的課題を抱える患者を地域の福祉的ケア等へと結び付ける活動をsocial prescribing(社会的処方)と呼び、特に英国でこの活動が推進されている。最初に、英国の社会的処方活動の現状について解説した。また日本を含む諸外国での現状と、国内で実践されている社会的処方に類似の活動を紹介した。これらをもとに、日本において患者の社会的背景に対する統合的なケアのニーズの把握とその対応を、標準的な手続きで推進するための課題について考察した。

  経済的に困窮した人ほど健康を害しやすいが、必要な医療受診を控えやすい。困窮する患者の医療受診を経済的に支援する無料低額診療事業（無低診）は、医療機関が定める基準を満たした患者の医療費の窓口負担を減免できる社会福祉制度である。経済的に困窮した人は、社会からの排除など多次元的な貧困に直面しており、医療費への経済的な支援は健康な生活を十分に保障できていない可能性がある。無低診を実施する医療機関により、実態や支援効果が異なる可能性もあるが、検証するためのデータはない。これまで申請者は無低診の利用者にフォーカスした研究を進めてきたが、研究成果の日本全体への一般化が課題であった。そこで本研究では、無低診利用者の全国的な実態を明らかにするために、無低診の利用者データの全国レジストリを構築することを目的とした。 2021年度は、全国の無料低額診療事業実施施設に対して、オンラインおよび現地での研究説明会を開催した。無料低額診療事業実施施設の医療ソーシャルワーカーを中心に収集すべき事項を討議し、無低診利用者のレジストリのしくみを構築した。 2022年度4月からは研究参加機関の利用者のデータがレジストリへと登録される。約50実施医療機関が研究参加しており、今後も増える見込みである。

  生活困窮者は様々な健康課題を抱えていることが多く、その実態把握と支援法の開発が求められる。自治体が所有する生活保護受給者の住民基本データや医療扶助・介護扶助レセプトデータを用いて、1)生活保護受給者の社会関係や生活背景についての新たな詳細データを追加し、最適な支援プランを提示するアルゴリズムを開発する。また、2)支援プランの効果の有無、および効果に影響を及ぼす要因を明らかにする。 生活保護受給者は定期的に担当のケースワーカーと面談していることを利用して、標準化された妥当な心理社会的背景の評価尺度を用いて受給者個人の心理社会状況や生活歴のデータを収集する。これらの生活歴に関するデータを受給者の住民基本データや医療（介護）扶助レセプトデータと結合したデータの提供を受ける。受給者の健康状態や受診行動（頻回受診・重複受診・重複処方・受診抑制・救急車利用等）に関連する要因の分析をする。これまでに収集されたデータをもとに、小児の慢性疾患や歯科疾患、成人の糖尿病発生や頻回受診に、孤立や慢性的な社会ストレスが関与している可能性が見いだされた。また、確率的潜在意味分析を用いて一般成人と高齢者の男女それぞれに、合理的な説明が可能な5つ程度の特徴的な受給者クラスターを導出し、特定のクラスターと頻回受診や健康アウトカムとの関連があることが明らかとなった。さらに、社会関係が豊かなほど、必要な時に生活保護を受けやすく、また経済的に自立し生活保護を終了できる可能性が高いこと、生活保護を終了した人は社会関係が広がること等を明らかにした。生活保護を受給している高齢者はその他の高齢者に比べて抑うつのリスクが極めて高いことも明らかにした。2021年度後半には詳細な生活状況に関する質問紙調査のデータ収集が軌道に乗った。
